The Young Supernova Experiment: Survey Goals, Overview, and Operations

D. O. Jones, R. J. Foley, G. Narayan +68

Time domain science has undergone a revolution over the past decade, with tens of thousands of new supernovae (SNe) discovered each year. However, several observational domains, in…

SN 2019ehk: A Double-Peaked Ca-rich Transient with Luminous X-ray Emission and Shock-Ionized Spectral Features

Wynn V. Jacobson-Galán, Raffaella Margutti, Charles D. Kilpatrick +64

We present panchromatic observations and modeling of the Calcium-rich supernova 2019ehk in the star-forming galaxy M100 (d16.2 Mpc) starting 10 hours after explosion and c…

A GMRT 150 MHz Search for Variables and Transients in Stripe 82

A. Hajela, K. P. Mooley, H. T. Intema +1

We have carried out a dedicated transient survey of 300 deg of the SDSS Stripe 82 region using the Giant Meterwavelength Radio Telescope (GMRT) at 150 MHz. Our multi-epoch obse…

Two years of non-thermal emission from the binary neutron star merger GW170817: rapid fading of the jet afterglow and first constraints on the kilonova fastest ejecta

A. Hajela, R. Margutti, K. D. Alexander +27

We present Chandra and VLA observations of GW170817 at ~521-743 days post merger, and a homogeneous analysis of the entire Chandra data set. We find that the late-time non-thermal…

The Optical Afterglow of GW170817: An Off-axis Structured Jet and Deep Constraints on a Globular Cluster Origin

Wen-fai Fong, P. K. Blanchard, K. D. Alexander +25

We present a revised and complete optical afterglow light curve of the binary neutron star merger GW170817, enabled by deep Hubble Space Telescope (HST) F606W observations at $\app…

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…
