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…
Gemini Near Infrared Spectrograph -- Distant Quasar Survey: Rest-Frame Ultraviolet-Optical Spectral Properties of Broad Absorption Line Quasars
Harum Ahmed, Ohad Shemmer, Brandon Matthews +12
We present the rest-frame ultraviolet-optical spectral properties of 65 broad absorption line (BAL) quasars from the Gemini Near Infrared Spectrograph-Distant Quasar Survey (GNIRS-…
Asteroids' Size Distribution and Colors from HiTS
J. Peña, C. Fuentes, F. Förster +8
We report the observations of solar system objects during the 2015 campaign of the High cadence Transient Survey (HiTS). We found 5740 bodies (mostly Main Belt asteroids), 1203 of…
A Fast-Evolving, Luminous Transient Discovered by K2/Kepler
A. Rest, P. M. Garnavich, D. Khatami +12
For decades optical time-domain searches have been tuned to find ordinary supernovae, which rise and fall in brightness over a period of weeks. Recently, supernova searches have im…
