The new era of Lyman alpha emitters (LAEs): Efficiency in the selection criteria
P. Layana-Astudillo, I. Laferte-Urrutia, L. Guaita +6
The ODIN survey has detected thousands of Lyman-alpha emitting galaxies across seven sky fields, covering nearly one hundred square degrees. One of these regions is the SHELA field…
WLM: Dynamics of an isolated Dwarf Irregular Galaxy Under Ram Pressure in the Local Group
Neel Kolhe, Francois Hammer, Yanbin Yang +5
WLM is an archetypal dwarf irregular galaxy that has not experienced interactions with major Local Group galaxies within the past 8 Gyr. It has recently been shown that WLM is losi…
Early Light Curve Excess in Type IIb Supernovae Observed by the ATLAS Survey: Qualitative Constraints on Progenitor Systems
Bastian Ayala, Joseph P. Anderson, G. Pignata +8
Type IIb supernovae (SNe IIb) often exhibit an early light curve excess (EE) preceding the main peak powered by radioactive nickel decay. The physical origin of this early emission…
The Milky Way accretion history compared to cosmological simulations -- from bulge to dwarf galaxy infall
F. Hammer, Y. J. Jiao, G. A. Mamon +6
Galactic halos are known to grow hierarchically, inside out. This implies a correlation between the infall lookback time of satellites and their binding energy. Cosmological simula…
