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…
Three Core-Collapse Supernovae with Nebular Hydrogen Emission
J. Sollerman, S. Yang, S. Schulze +25
We present SN 2020jfo, a Type IIP supernova in the nearby galaxy M61. Optical light curves from the Zwicky Transient Facility, complemented with data from Swift and near-IR photome…
SRG/ART-XC discovery of SRGA J204318.2+443815: towards the complete population of faint X-ray pulsars
A. A. Lutovinov, S. S. Tsygankov, I. A. Mereminskiy +19
We report a discovery of a new long-period X-ray pulsar SRGA J204318.2+443815/SRGe J204319.0+443820 in the Be binary system. The source was found in the second all-sky survey by th…
