TESS detection of periodic brightness variations during the rise of classical nova PGIR22akgylf
Kirill V. Sokolovsky, Elias Aydi, Konstantin Malanchev +14
Classical novae are transient events powered by thermonuclear burning in a layer of hydrogen-rich material accreted by a white dwarf from its binary companion. Most classical novae…
Low-Luminosity Type IIP Supernovae from the Zwicky Transient Facility Census of the Local Universe. III: Hunting for electron-capture supernovae using nebular spectroscopy
Kaustav K. Das, Anders Jerkstrand, Mansi M. Kasliwal +18
Electron-capture supernovae (ECSNe) may arise from ONeMg-core collapse in super-asymptotic giant branch (sAGB) stars near the low-mass core-collapse limit (--\,\Msu…
Nebular Phase Evolution of SN 2023ixf (I): From Circumstellar Infrared Echo to the onset of in-situ Dust Formation in a Type II Supernova
Avinash Singh, S. Goto, A. Sarangi +58
We present optical and near-infrared (NIR) photometric and spectroscopic observations of the Type II supernova SN 2023ixf spanning 150 to 750 days, combined with published early-ti…
A New FU Orionis Accretion Outburst in the W5 HII Region
Lynne A. Hillenbrand, Matthew J. Graham, Mansi M. Kasliwal +9
We announce a recently detected outburst that is currently only a few months old, and probably of FU Orionis type. The progenitor to the outburst was an emission-line, flat-spectru…
ZTF25abjmnps (AT2025ulz) and S250818k: A Candidate Superkilonova from a Sub-threshold Sub-Solar Gravitational Wave Trigger
Mansi M. Kasliwal, Tomas Ahumada, Robert Stein +61
On August 18, 2025, the LIGO-Virgo-KAGRA collaboration reported gravitational waves from a sub-threshold binary neutron star merger. If astrophysical, this event would have a surpr…
A spectral library and census of near-infrared stellar large-amplitude variables from Palomar Gattini-IR
Nicholas Earley, Viraj Karambelkar, Mansi Kasliwal +9
We present a near-infrared census of stellar large-amplitude variables (LAVs) observed by the Palomar Gattini-IR (PGIR) surveyor from 2019-2021. Over the three-year time period, PG…
Cryoscope: A Cryogenic Infrared Survey Telescope in Antarctica
Mansi M. Kasliwal, Nicholas Earley, Roger Smith +58
We present Cryoscope--a new 50 deg field-of-view, 1.2 m aperture, survey telescope to be located at Dome C, Antarctica. Cryoscope has an innovative optical-thermal d…
Low-Luminosity Type IIP Supernovae from the Zwicky Transient Facility Census of the Local Universe. I: Luminosity Function, Volumetric Rate
Kaustav K. Das, Mansi M. Kasliwal, Christoffer Fremling +51
We present the luminosity function and volumetric rate of a sample of Type IIP supernovae (SNe) from the Zwicky Transient Facility Census of the Local Universe survey (CLU). This i…
Possible anti-correlations between pulsation amplitudes and the disk growth of Be stars in giant-outbursting Be X-ray binaries
Masafumi Niwano, Michael M. Fausnaugh, Ryan M. Lau +15
The mechanism of X-ray outbursts in Be X-ray binaries remains a mystery, and understanding their circumstellar disks is crucial for a solution of the mass-transfer problem. In part…
An infrared census of R Coronae Borealis Stars II -- Spectroscopic classifications and implications for the rate of low-mass white dwarf mergers
Viraj R. Karambelkar, Mansi M. Kasliwal, Patrick Tisserand +18
We present results from a systematic infrared (IR) census of R Coronae Borealis (RCB) stars in the Milky Way, using data from the Palomar Gattini IR (PGIR) survey. R Coronae Boreal…
The first Palomar Gattini-IR catalog of J-band light curves: construction and public data release
Shion Murakawa, Kishalay De, Michael C. B. Ashley +7
Palomar Gattini-IR (PGIR) is a wide-field, synoptic infrared time domain survey covering \,sq.\,deg. of the \textbf{accessible} sky at \,night cadence t…
WTP19aalnxx: Discovery of a bright mid-infrared transient in the emerging class of low luminosity supernovae revealed by delayed circumstellar interaction
Charlotte Myers, Kishalay De, Lin Yan +11
While core-collapse supernovae (SNe) often show early and consistent signs of circumstellar (CSM) interaction, some exhibit delayed signatures due to interaction with distant mater…
A Long-term Study of Ultraluminous X-ray Sources in NGC 891
Nicholas M. Earley, Vikram V. Dwarkadas, Victoria Cirillo
We perform empirical fits to the \emph{Chandra} and \emph{XMM-Newton} spectra of three ultraluminous X-ray sources (ULXs) in the edge-on spiral galaxy NGC 891, monitoring the regio…
