Title: Black Hole Evolution through Cosmic Time - 06-27-2025
Guest Speaker: Junsheng (Sam) He, Student, University of Melbourne, Australia.
Summary: A fascinating talk by Junsheng (Sam) He from the University of Melbourne, exploring how black holes grow and evolve across the history of the universe. Discover how these cosmic giants have transformed over billions of years to become the supermassive black holes we observe today. If you are interested in the study of black holes, this video will be for you. We hope you enjoy it!

$Fun with The SUN Speakers: Dr. Christian Sasse, Astronomer-in-charge, and Leigh Moore, Software Developer iTelescope iTelescope Announcement: In this video, Christian and Leigh announce the addition of a dedicated remote-access Solar Telescope located at Siding Springs! The Sun Telescope is an Explore Scientific Refractor at f/7.5 with a Daystar Filter calibrated to 0.4 angstroms which provides massive contrast with a Barlow that extends the focal length to f/32. The field of view is 1/27th of the sun. Anyone will be allowed to operate the Sun Telescope independently in 1-hour sessions using a pay-as-you-go system of payment. iTelescope will offer guides and videos on processing the data from this telescope. iTelescope is unique in offering access to a remote solar telescope to everyone. We hope you will take advantage of this unique opportunity! iTelescope https://www.itelescope.net #iTelescope #astrophotography #deepsky #astro #astronomy #cosmology$

$Almost touching stars - Astronomical Spectroscopy Guest Speaker: Tom Field, RSpec-Astro.com Summary: Learn how to do science with your own equipment. In this talk, Tom explains how to do spectroscopy with relatively simple star analyzers (diffraction grating) and what you can do with star spectra. As he describes in the video, hidden inside the rainbow of a star color is the biography of the life of that star, where the gaps inside the spectra are the star’s chemical fingerprints. Tom shows that to do science with star spectra, one has to create the light curve to capture the dips (absorption lines) in the light curve at different wavelengths, which, when mapped to the spectrum of different chemicals, the chemistry of the star can be analyzed. This is an exciting field to explore and to extend your astronomy interest. iTelescope https://www.itelescope.net RSpec Website https://www.rspec-astro.com RSpec Google user group https://groups.io/g/RSpec-Astronomy Chapters 0:00 Introduction 7:40 Example spectra 8:16 Star Analyzer and equipment needed 11:02 Chemical fingerprints 19:45 Overview of diffraction 20:16 Spectroscopic analysis 23:48 Great astronomers 25:53 What can you do with a Star Analyzer? 29:40 Emission and absorption Spectrum 30:49 From raw photons to qualitative data 33:05 RSpec software 38:16 Spectrum beyond stars 38:52 High-resolution Slit Devices 42:05 Planet Spectrum 44:01 Comet Spectrum 46:24 Flash Spectrum 46:52 Doppler shift and Spectrum 48:03 Type 1a supernova 52:41 Blackhole Spectrum 57:30 Stellar rotation 59:31 Detailed how to get started #iTelescope #astrophotography #deepsky #astro #astronomy #cosmology #spectroscopy$
