Serendipitous detection of the dusty Type IIL SN 1980K with JWST/MIRI
Szanna Zsíros, Tamás Szalai, Ilse De Looze +39
We present mid-infrared (mid-IR) imaging of the Type IIL supernova (SN) 1980K with the James Webb Space Telescope (JWST) more than 40 yr post-explosion. SN 1980K, located in the ne…
JWST Discovery of Dust Reservoirs in Nearby Type IIP Supernovae 2004et and 2017eaw
Melissa Shahbandeh, Arkaprabha Sarangi, Tea Temim +36
Supernova (SN) explosions have been sought for decades as a possible source of dust in the Universe, providing the seeds of galaxies, stars, and planetary systems. SN 1987A offers…
SRGA J181414.6-225604: A new Galactic symbiotic X-ray binary outburst triggered by an intense mass loss episode of a heavily obscured Mira variable
Kishalay De, Ilya Mereminskiy, Roberto Soria +24
We present the discovery and multi-wavelength characterization of SRGA J181414.6-225604, a Galactic hard X-ray transient discovered during the ongoing SRG/ART-XC sky survey. Using…
A massive AGB donor in Scutum X-1: Identification of the first Mira variable in an X-ray binary
Kishalay De, Deepto Chakrabarty, Roberto Soria +9
The symbiotic X-ray binary Sct X-1 was suggested as the first known neutron star accreting from a red supergiant companion. Although known for nearly 50 years, detailed characteriz…
Second Timescale Photometry of the Very Fast Nova V1674 Her with Palomar Gattini-IR
Kylie Y. Hansen, Kishalay De, Michael C. B. Ashley +15
We report second-timescale infrared photometry of the nova V1674 Her using Palomar Gattini-IR. These observations constitute the first infrared and highest temporal resolution data…
PGIR 20eid (SN2020qmp): A Type IIP Supernova at 15.6 Mpc discovered by the Palomar Gattini-IR survey
G. P. Srinivasaragavan, I. Sfaradi, J. Jencson +19
We present a detailed analysis of SN 2020qmp, a nearby type IIP core-collapse supernova (CCSN), discovered by the Palomar Gattini-IR (PGIR) survey in the galaxy UGC07125. We illust…
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…
From SN2010da to NGC 300 ULX-1: Ten Years of Observations of an Unusual High Mass X-ray Binary in NGC 300
Breanna A. Binder, Stefania Carpano, Marianne Heida +1
In 2010 May, an intermediate luminosity optical transient was discovered in the nearby galaxy NGC 300 by a South African amateur astronomer. In the decade since its discovery, mult…
Uncovering Red and Dusty Ultraluminous X-ray Sources with Spitzer
Ryan M. Lau, Marianne Heida, Dominic J. Walton +9
We present a mid-infrared (IR) sample study of nearby ultraluminous X-ray sources (ULXs) using multi-epoch observations with the Infrared Array Camera (IRAC) on the Spitzer Space T…
The Dynamic Infrared Sky
Mansi M. Kasliwal, Scott Adams, Igor Andreoni +16
Opening up the dynamic infrared sky for systematic time-domain exploration would yield many scientific advances. Multi-messenger pursuits such as localizing gravitational waves fro…
