GROWTH on S190814bv: Deep Synoptic Limits on the Optical/Near-Infrared Counterpart to a Neutron Star-Black Hole Merger
Igor Andreoni, Daniel A. Goldstein, Mansi M. Kasliwal +49
On 2019 August 14, the Advanced LIGO and Virgo interferometers detected the high-significance gravitational wave (GW) signal S190814bv. The GW data indicated that the event resulte…
GROWTH on S190510g: DECam Observation Planning and Follow-Up of a Distant Binary Neutron Star Merger Candidate
Igor Andreoni, Daniel A. Goldstein, Shreya Anand +23
The first two months of the third Advanced LIGO and Virgo observing run (2019 April-May) showed that distant gravitational wave (GW) events can now be readily detected. Three candi…
GROWTH on S190425z: Searching thousands of square degrees to identify an optical or infrared counterpart to a binary neutron star merger with the Zwicky Transient Facility and Palomar Gattini IR
Michael W. Coughlin, Tomás Ahumada, Shreya Anand +76
The third observing run by LVC has brought the discovery of many compact binary coalescences. Following the detection of the first binary neutron star merger in this run (LIGO/Virg…
The Case for a High-Redshift Origin of GRB100205A
A. A. Chrimes, A. J. Levan, E. R. Stanway +15
The number of long gamma-ray bursts (GRBs) known to have occurred in the distant Universe (z greater than 5) is small (approx 15), however these events provide a powerful way of pr…
GROWTH on S190426c. II. Real-Time Search for a Counterpart to the Probable Neutron Star-Black Hole Merger using an Automated Difference Imaging Pipeline for DECam
Daniel A. Goldstein, Igor Andreoni, Peter E. Nugent +17
The discovery of a transient kilonova following the gravitational-wave event GW170817 highlighted the critical need for coordinated rapid and wide-field observations, inference, an…
Achieving Transformative Understanding of Extreme Stellar Explosions with ELT-enabled Late-time Spectroscopy
D. Milisavljevic, R. Margutti, R. Chornock +35
Supernovae are among the most powerful and influential explosions in the universe. They are also ideal multi-messenger laboratories to study extreme astrophysics. However, many fun…
The volumetric rate of normal type Ia supernovae in the local universe discovered by the Palomar Transient Factory
C. Frohmaier, M. Sullivan, P. E. Nugent +10
We present the volumetric rate of normal type Ia supernovae (SNe Ia) discovered by the Palomar Transient Factory (PTF). Using strict data-quality cuts, and considering only periods…
Multi-Messenger Astronomy with Extremely Large Telescopes
Ryan Chornock, Philip S. Cowperthwaite, Raffaella Margutti +82
The field of time-domain astrophysics has entered the era of Multi-messenger Astronomy (MMA). One key science goal for the next decade (and beyond) will be to characterize gravitat…
WFIRST: Enhancing Transient Science and Multi-Messenger Astronomy
Ryan J. Foley, Joshua S. Bloom, S. Bradley Cenko +31
Astrophysical transients have been observed for millennia and have shaped our most basic assumptions about the Universe. In the last century, systematic searches have grown from de…
A multi-wavelength analysis of a collection of short-duration GRBs observed between 2012-2015
S. B. Pandey, Y. Hu, A. J. Castro-Tirado +71
We investigate the prompt emission and the afterglow properties of short duration gamma-ray burst (sGRB) 130603B and another eight sGRB events during 2012-2015, observed by several…
