A population of heavily reddened, optically missed novae from Palomar Gattini-IR: Constraints on the Galactic nova rate
Kishalay De, Mansi M. Kasliwal, Matthew J. Hankins +25
The nova rate in the Milky Way remains largely uncertain, despite its vital importance in constraining models of Galactic chemical evolution as well as understanding progenitor cha…
Constraining the Kilonova Rate with Zwicky Transient Facility Searches Independent of Gravitational Wave and Short Gamma-ray Burst Triggers
Igor Andreoni, Erik C. Kool, Ana Sagues Carracedo +34
The first binary neutron star merger, GW170817, was accompanied by a radioactivity-powered optical/infrared transient called a kilonova. To date, no compelling kilonova has been fo…
Constraining the X-ray - Infrared spectral index of second-timescale flares from SGR1935+2154 with Palomar Gattini-IR
Kishalay De, Michael C. B. Ashley, Igor Andreoni +16
The Galactic magnetar SGR1935+2154 has been reported to produce the first known example of a bright millisecond duration radio burst (FRB 200428) similar to the cosmological popula…
ZTF20aajnksq (AT2020blt): A Fast Optical Transient at With No Detected Gamma-Ray Burst Counterpart
Anna Y. Q. Ho, Daniel A. Perley, Paz Beniamini +27
We present ZTF20aajnksq (AT2020blt), a fast-fading ( mag in days) red ( mag) and luminous () optical transient at discovered…
The Zwicky Transient Facility Census of the Local Universe I: Systematic search for Calcium rich gap transients reveal three related spectroscopic sub-classes
Kishalay De, Mansi M. Kasliwal, Anastasios Tzanidakis +47
(Abridged) Using the Zwicky Transient Facility alert stream, we are conducting a large campaign to spectroscopically classify all transients occurring in galaxies in the Census of…
SN2020bvc: a Broad-lined Type Ic Supernova with a Double-peaked Optical Light Curve and a Luminous X-ray and Radio Counterpart
A. Y. Q. Ho, S. R. Kulkarni, D. A. Perley +34
We present optical, radio, and X-ray observations of SN2020bvc (=ASASSN20bs; ZTF20aalxlis), a nearby (; =114 Mpc) broad-lined (BL) Type Ic supernova (SN). Our observat…
