NGC 1851E: Making a black hole mass gap binary OzGrav ARC Centre of Excellence 2024-01-18 | NGC 1851E is a binary star system containing a rapidly spinning millisecond pulsar in orbit around a optically dark companion of unknown nature. The companion's mass puts it between the heaviest known neutron stars and lightest known black holes, in the so-called black hole mass gap.Here we show an orbital simulation detailing a possible formation channel for the NGC 1851E system. We see the original pulsar - white dwarf binary in a globular cluster being disrupted by the arrival of a massive third body. The new arrival kicks the white dwarf out of orbit and captures the pulsar for itself, forming a new binary system with a pulsar in orbit around, most likely, either a light black hole or a supermassive neutron star.The NGC 1851E system was discovered by the Transients and Pulsars with MeerKAT (TRAPUM) collaboration using the MeerKAT radio telescope in South Africa.This work was led by researchers from the Max Planck Institute for Radio Astronomy (MPIfR) and is published in the journal Science.Video credit: OzGrav, Swinburne University of TechnologyTransients and Pulsars with MeerKAT (TRAPUM): http://www.trapum.orgMax Planck Institute for Radio Astronomy (MPIfR):http://www.mpifr-bonn.mpg.de/2169/enMeerKAT, South Africa: https://www.sarao.ac.za/science/meerkat/Full science paper available at: science.org/doi/10.1126/science.adg3005

Convex Hull OzGrav ARC Centre of Excellence 2023-06-29 | A convex hull in 3D space can be thought of like an invisible, flexible shrink-wrap that perfectly encloses a group of objects or points. Imagine you have several sets of black holes floating in space, and you wrap them in the smallest possible piece of shrink-wrap that covers all of them. That shrink-wrap forms the 'convex hull'. This concept is frequently used in fields such as 3D graphics, virtual reality, robotics, and scientific data analysis. It helps in understanding the boundaries and spatial relationships among objects. For example, it's used in video games and virtual reality to detect when 3D models overlap, or in robotics to figure out the volume of space a robot can reach.OzGrav researchers use the concept of a convex hull as a crucial tool in making sense of our three-dimensional world.

SciVR - National Science Week 2020 - Families OzGrav ARC Centre of Excellence 2020-08-22 | A family-friendly guided tour of the Universe. Download the free app at www.scivr.com.au. Here are some more answers to questions we didn't have time to cover:Devlin - there are flashes of light every once and a while?Those are transients.Transients of what?They can be from multiple sources - dead stars can merge giving off a flash, magnetised stars may emit a type of radiation once a while, alive stars can create a flash while dying. So any astrophysical object(s) that has a momentary change in luminosity can be the source of a transient.Ming n Mel - What would happen if you enter a Black hole?As you approach the black hole, the strength of its gravitational pull would stretch you out like spaghetti. Time would run differently for you such that you would see the events of the universe run very very quickly, getting faster and faster as you got closer to the center of the black hole where the singularity occurs. If you manage to enter without dying from the spaghettification, we just do not know! That is the biggest mystery in physics that all known laws of physics break down inside a black hole.
SciVR - National Science Week 2020 OzGrav ARC Centre of Excellence 2020-08-21 | Thanks for joining for our livestream with Rebecca Allen and Alan Duffy. Big thanks to Auslan Consulting and Auslan Services for their great sign language interpreters. Watch back again any time. Download the free app at www.scivr.com.au. Here are some of your questions we didn't cover during the live talk:Why are the stars in the home screen area all blue or red? Why aren’t any yellow or green?So the reason that all the stars appear blue or red (and white) is that stars in the Universe are one of these three colours normally. The hottest stars are blue, the colder stars are red, and the stars in the middle appear white. Stars that we call “yellow” actually look very white because there is also lots of blue and red light coming from them. There aren’t actually any stars that appear green.What's cooler, black holes or neutron stars?Depends on your preference but they are both absolutely fascinating objects but Vaishali personally picks neutron stars!In a literal sense, Black Holes are nearly absolute zero, but pulsars are up to 10 trillion K (Kelvin).Have scientists yet seen two neutron stars collide together? and if yes what happens.We have seen a couple of events from merging neutron stars, one of which (GW170817) was also seen in visible light AND gamma rays! The “kilonova” that accompanied this event was the first one ever seen, and was followed up by 70 telescopes all around the world and in space. We’ve learned a lot but are desperate to catch more events!How does LIGO know if it is a black hole or neutron star?From the shape we can get information about the masses and the masses gives us an idea of whether it is a black hole or a neutron star. We can get an estimate on the masses from the signal, and we know that Neutron Stars are systematically smaller than Black Holes. Relative to the sun, which has a mass of 1 solar mass, Neutron Stars have a mass less than about 2 solar masses, while Black Holes have masses usually well over 5 solar masses. But we don’t actually know the strict cutoff number (the maximum amount of mass a Neutron Star could have before collapsing into a Black Hole), so we don’t always have a good guess.What benefit can we gain from detecting far away black holes and neutral stars?We can discover objects that we otherwise can’t see (with normal telescopes), and learn more about the physics which describes our universe. Also the spin-off technology that is developed as a part of building a detector for such objects. For example, the development of incredibly sensitive sensors for seismic waves gives us an early warning system for things like earthquakes.

OzHF: What can a proposed high frequency gravitational wave detector tell us about neutron stars? OzGrav ARC Centre of Excellence 2020-07-06 | Talk from ARC Future Fellow Dr Paul Lasky, OzGrav and Monash University. Part of a series of talks for the AIP from ARC Centres of Excellence.Since the first detection of gravitational waves in 2015 from colliding black holes a billion light years away, the field of gravitational-wave astronomy has gone from strength to strength. The watershed discovery of colliding neutron stars in 2017 that was seen with gravitational waves and across the electromagnetic spectrum gave new insights into the speed of gravity, how matter behaves at supranuclear densities, and cosmology. Paul will describe a detailed plan to build OzHF: a kilohertz-band extreme matter observatory in Australia. OzHF will measure the fundamental properties of nuclear matter at extreme densities. Its presence in the global array of gravitational-wave detectors will maximise the observatory's scientific impact, while also providing an avenue for technology development for the full third-generation of gravitational-wave detectors currently being explored across the globe.For more information subscribe/follow us on YouTube, Facebook, Twitter, Instagram and www.ozgrav.org

OzGrav: A new wave of discovery OzGrav ARC Centre of Excellence 2020-04-06 | The Australian Research Council (ARC) Centre of Excellence for Gravitational Wave Discovery (OzGrav) presents its inaugural short documentary ‘OzGrav: A new wave of discovery’. Building on one of Albert Einstein’s greatest intellectual achievements in physics—the theory of general relativity—OzGrav brings together Australian astrophysics and gravitational-wave communities into a unified national science program. Gravitational waves (GWs) are ripples in space-time generated by accelerating masses, such as two immensely dense black holes that collide into each other. These waves stretch and squeeze space-time as they radiate outwards at the speed of light. These distortions felt on Earth are so tiny, they require the most sensitive instrumentation ever built to detect them: it’s like trying to measure the distance between the Sun and its nearest star, Proxima Centauri (4.243 light years away), to an accuracy of the width of a hair. Unbelievably, after recent advances in detector sensitivity, GWs were detected for the first time in September 2015—a landmark achievement in scientific discovery that heralded the birth of gravitational-wave astronomy.In 2016, the ARC funded OzGrav, supporting some of the world’s leading scientists and engineers to work on gravitational-wave research as part of the international LIGO-Virgo-KAGRA collaboration. Since then, OzGrav has made exceptional scientific contributions to gravitational-wave research including the detection of more GWs and planning future GW detectors. OzGrav’s innovative research and technological advancements are also benefitting a range of industries worldwide, including aviation, mining, defence, and self-driving cars. OzGrav continues to fulfil its mission: to inspire and lead the next generation of Australian scientists and engineers through this new window of the Universe. We acknowledge and thank the tremendous work by Carl Knox who produced and directed this documentary, as well as everyone in OzGrav who contributed, both in front and behind the scenes.

Merging Neutron Stars create Gravitational Waves (no sound) OzGrav ARC Centre of Excellence 2020-02-05 | 2 stars orbiting each other make a binary system. As they get closer together they emit gravitational waves, which stretch and squash everything in space and time. LIGO detects gravitational waves. When the neutron stars merge together they form one neutron star, and the gravitational wave signal stops.Follow LIGO’s detections at ligo.org and download the Chirp app. www.ozgrav.orgAnimation credit: Carl Knox, OzGrav - ARC Centre of Excellence for Gravitational Wave Discovery.
