An infrared census of R Coronae Borealis Stars II -- Spectroscopic classifications and implications for the rate of low-mass white dwarf mergers
Viraj R. Karambelkar, Mansi M. Kasliwal, Patrick Tisserand +18
We present results from a systematic infrared (IR) census of R Coronae Borealis (RCB) stars in the Milky Way, using data from the Palomar Gattini IR (PGIR) survey. R Coronae Boreal…
Spectroscopic observations of progenitor activity 100 days before a Type Ibn supernova
S. J. Brennan, J. Sollerman, I. Irani +30
Obtaining spectroscopic observations of the progenitors of core-collapse supernovae is often unfeasible due to an inherent lack of knowledge as to which stars will go supernova and…
Search for Eccentric Black Hole Coalescences during the Third Observing Run of LIGO and Virgo
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1772
Despite the growing number of confident binary black hole coalescences observed through gravitational waves so far, the astrophysical origin of these binaries remains uncertain. Or…
Chemical Distribution of the Dynamical Ejecta in the Neutron Star Merger GW170817
Shreya Anand, Peter T. H. Pang, Mattia Bulla +11
GW170817 and its associated electromagnetic counterpart AT2017gfo continue to be a treasure trove as observations and modeling continue. Recent precision astrometry of AT2017gfo wi…
A Sensitive Search for Supernova Emission Associated with the Extremely Energetic and Nearby GRB 221009A
Gokul P. Srinivasaragavan, Brendan O' Connor, S. Bradley Cenko +24
We report observations of the optical counterpart of the long gamma-ray burst (LGRB) GRB 221009A. Due to the extreme rarity of being both nearby () and highly energetic…
