To unlock the secrets of the (local) universe, Adam Riess observes the brightness of supernovae and Cepheid variables to measure the distance to galaxies far, far away. Read more about his research before his plenary talk at #AAS231 on Tuesday.
Trying to find the most massive galaxy cluster in the night sky can be hard. Comparing predictions of these masses to observed clusters? Even harder. An insight into the world of Halo Mass Functions and their tail-ends.
The universe is filled with tiny, faint dwarf galaxies. The authors of this paper are on the hunt for them.
Microlensing could hold the key to studying planet formation in incredibly crowded regions of the galaxy, and today’s paper shows us how.
In the quest to obtain precise measurements of the Hubble Constant, Type Ia supernoave have been consistently used as optical standard candles. What if near-infrared observations of SNe joined the race?
Magnetic fields always make things more compiclated. In today’s paper, the authors studied their effect on the atmosphere of white dwarf stars.
