On Odd Radio Circles as Supernova Remnants

Sumit K. Sarbadhicary, Todd A. Thompson, Laura A. Lopez +1

The origin of arcmin-sized Odd Radio Circles (ORCs) found in modern all-sky radio surveys remain uncertain, with explanations ranging from starburst/AGN-driven shocks to supernova…

Physical Properties of the Host Galaxies of Ca-rich Transients

Y. Dong, D. Milisavljevic, J. Leja +8

Calcium-rich (Ca-rich) transients are a new class of supernovae (SNe) that are known for their comparatively rapid evolution, modest peak luminosities, and strong nebular calcium e…

The RR Lyrae Delay-Time Distribution: A Novel Perspective on Models of Old Stellar Populations

Sumit K. Sarbadhicary, Mairead Heiger, Carles Badenes +6

The delay-time distribution (DTD) is the occurrence rate of a class of objects as a function of time after a hypothetical burst of star formation. DTDs are mainly used as a statist…

A Bright Ultraviolet Excess in the Transitional 02es-like Type Ia Supernova 2019yvq

J. Burke, D. A. Howell, S. K. Sarbadhicary +14

We present photometric and spectroscopic observations of the nearby Type Ia SN 2019yvq, from its discovery 1 day after explosion to 100 days after its peak brightness.…

Quasars That Have Transitioned from Radio-quiet to Radio-loud on Decadal Timescales Revealed by VLASS and FIRST

Kristina Nyland, Dillon Z. Dong, Pallavi Patil +21

We have performed a search over 3440 deg of Epoch 1 (2017-2019) of the Very Large Array Sky Survey to identify unobscured quasars in the optical () and obscured…

Constraining the Source of the High-velocity Ejecta in Type Ia SN 2019ein

C. Pellegrino, D. A. Howell, S. K. Sarbadhicary +16

We present multiwavelength photometric and spectroscopic observations of SN 2019ein, a high-velocity Type Ia supernova (SN Ia) discovered in the nearby galaxy NGC 5353 with a two-d…
