RR Lyrae Stars in the Field of Sagittarius II
Seok-Joo Joo, Jaemann Kyeong, Soung-Chul Yang +10
We present the detection of RR Lyrae variable stars in the field of the Sagittarius II (Sgr II) ultra-faint dwarf (UFD) galaxy. Using B, V time-series photometry obtained with the…
Astro2020 Science White Paper: The Local Relics of of Supermassive Black Hole Seeds
Jenny E Greene, Aaron Barth, Andrea Bellini +18
We have compelling evidence for stellar-mass black holes (BHs) of ~5-80 M_sun that form through the death of massive stars. We also have compelling evidence for so-called supermass…
Star Formation in Different Environments: The Initial Mass Function
M. W. Hosek, J. R. Lu, M. Andersen +7
The stellar initial mass function (IMF) is a fundamental property of star formation, offering key insight into the physics driving the process as well as informing our understandin…
Testing the Nature of Dark Matter with Extremely Large Telescopes
Joshua D. Simon, Simon Birrer, Keith Bechtol +12
For nearly 40 years, dark matter has been widely assumed to be cold and collisionless. Cold dark matter models make fundamental predictions for the behavior of dark matter on small…
