Limit on Supernova Emission in the Brightest Gamma-ray Burst, GRB 221009A

Manisha Shrestha, David J. Sand, Kate D. Alexander +30

We present photometric and spectroscopic observations of the extraordinary gamma-ray burst (GRB) 221009A in search of an associated supernova. Some past GRBs have shown bumps in th…

Core-collapse Supernovae in the Dark Energy Survey: Luminosity Functions and Host Galaxy Demographics

M. Grayling, C. P. Gutiérrez, M. Sullivan +73

We present the luminosity functions and host galaxy properties of the Dark Energy Survey (DES) core-collapse supernova (CCSN) sample, consisting of 69 Type II and 50 Type Ibc spect…

Understanding the extreme luminosity of DES14X2fna

M. Grayling, C. P. Gutiérrez, M. Sullivan +66

We present DES14X2fna, a high-luminosity, fast-declining type IIb supernova (SN IIb) at redshift , detected by the Dark Energy Survey (DES). DES14X2fna is an unusual memb…

Candidate Periodically Variable Quasars from the Dark Energy Survey and the Sloan Digital Sky Survey

Yu-Ching Chen, Xin Liu, Wei-Ting Liao +62

Periodically variable quasars have been suggested as close binary supermassive black holes. We present a systematic search for periodic light curves in 625 spectroscopically confir…

A DESGW Search for the Electromagnetic Counterpart to the LIGO/Virgo Gravitational Wave Binary Neutron Star Merger Candidate S190510g

DES Collaboration, A. Garcia, R. Morgan +87

We present the results from a search for the electromagnetic counterpart of the LIGO/Virgo event S190510g using the Dark Energy Camera (DECam). S190510g is a binary neutron star (B…

Constraints on the Physical Properties of GW190814 through Simulations based on DECam Follow-up Observations by the Dark Energy Survey

R. Morgan, M. Soares-Santos, J. Annis +99

On 14 August 2019, the LIGO and Virgo Collaborations detected gravitational waves from a black hole and a 2.6 solar mass compact object, possibly the first neutron star -- black ho…
