Census of R Coronae Borealis stars I: Infrared light curves from Palomar Gattini IR
Viraj R. Karambelkar, Mansi M. Kasliwal, Patrick Tisserand +16
We are undertaking the first systematic infrared (IR) census of R Coronae Borealis (RCB) stars in the Milky Way, beginning with IR light curves from the Palomar Gattini IR (PGIR) s…
Revealing Efficient Dust-Formation at Low Metallicity in Extragalactic Carbon-Rich Wolf-Rayet Binaries
Ryan M. Lau, Matthew J. Hankins, Mansi M. Kasliwal +6
We present Spitzer/IRAC observations of dust formation from six extragalactic carbon-rich Wolf-Rayet (WC) binary candidates in low-metallicity (Z Z) environm…
Bright, months-long stellar outbursts announce the explosion of interaction-powered supernovae
Nora L. Strotjohann, Eran O. Ofek, Avishay Gal-Yam +53
Interaction-powered supernovae (SNe) explode within an optically-thick circumstellar medium (CSM) that could be ejected during eruptive events. To identify and characterize such pr…
Optical follow-up of the neutron star-black hole mergers S200105ae and S200115j
Shreya Anand, Michael W. Coughlin, Mansi M. Kasliwal +46
LIGO and Virgo's third observing run (O3) revealed the first neutron star-black hole (NSBH) merger candidates in gravitational waves. These events are predicted to synthesize r-pro…
Characterization of Temporarily-Captured Minimoon 2020 CD by Keck Time-resolved Spectrophotometry
Bryce T. Bolin, Christoffer Fremling, Timothy R. Holt +42
We present time-resolved visible spectrophotometry of minimoon 2020 CD, the second asteroid known to become temporarily captured by the Earth-Moon system's gravitational field.…
Resolving Decades of Periodic Spirals from the Wolf-Rayet Dust Factory WR 112
Ryan M. Lau, Matthew J. Hankins, Yinuo Han +9
WR 112 is a dust-forming carbon-rich Wolf-Rayet (WC) binary with a dusty circumstellar nebula that exhibits a complex asymmetric morphology, which traces the orbital motion and dus…
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…
A non-equipartition shockwave traveling in a dense circumstellar environment around SN2020oi
Assaf Horesh, Itai Sfaradi, Mattias Ergon +34
We report the discovery and panchromatic followup observations of the young Type Ic supernova, SN2020oi, in M100, a grand design spiral galaxy at a mere distance of Mpc. We fo…
Kilonova Luminosity Function Constraints based on Zwicky Transient Facility Searches for 13 Neutron Star Mergers
Mansi M. Kasliwal, Shreya Anand, Tomas Ahumada +100
We present a systematic search for optical counterparts to 13 gravitational wave (GW) triggers involving at least one neutron star during LIGO/Virgo's third observing run. We searc…
Revisiting the Impact of Dust Production from Carbon-Rich Wolf-Rayet Binaries
Ryan M. Lau, J. J. Eldridge, Matthew J. Hankins +3
We present a dust spectral energy distribution (SED) and binary stellar population analysis revisiting the dust production rates (DPRs) in the winds of carbon-rich Wolf-Rayet (WC)…
Helium-rich Superluminous Supernovae From the Zwicky Transient Facility
Lin Yan, D. Perley, S. Schulze +39
Helium is expected to be present in the ejecta of some hydrogen-poor superluminous supernovae (SLSN-I). However, so far only one event, PTF10hgi has been identified with He feature…
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…
Early Ultra-Violet observations of type IIn supernovae constrain the asphericity of their circumstellar material
Maayane T. Soumagnac, Eran O. Ofek, Jingyi Liang +41
We present a survey of the early evolution of 12 Type IIn supernovae (SNe IIn) in the Ultra-Violet (UV) and visible light. We use this survey to constrain the geometry of the circu…
SOFIA/FORCAST Galactic Center Legacy Survey: Overview
Matthew J. Hankins, Ryan M. Lau, James T. Radomski +12
The Galactic Center contains some of the most extreme conditions for star formation in our Galaxy as well as many other phenomena that are unique to this region. Given our relative…
