A precessing jet from an active galactic nucleus drives gas outflow from a disk galaxy
Justin A. Kader, Vivian U, Loreto Barcos-Muñoz +30
To reproduce observed galaxy properties, cosmological simulations require that massive galaxies experience feedback from active galactic nuclei, which regulates star formation with…
CCSNscore: A multi-input deep learning tool for classification of core-collapse supernovae using SED-Machine spectra
Yashvi Sharma, Ashish A. Mahabal, Jesper Sollerman +16
Supernovae (SNe) come in various flavors and are classified into different types based on emission and absorption lines in their spectra. SN candidates are now abundant with the ad…
How accurate are transient spectral classification tools? -- A study using 4,646 SEDMachine spectra
Young-Lo Kim, Isobel Hook, Andrew Milligan +13
Accurate classification of transients obtained from spectroscopic data are important to understand their nature and discover new classes of astronomical objects. For supernovae (SN…
SN 2023zaw: an ultra-stripped, nickel-poor supernova from a low-mass progenitor
Kaustav K. Das, Christoffer Fremling, Mansi M. Kasliwal +34
We present SN 2023zaw a sub-luminous ( mag) and rapidly-evolving supernova ( days), with the lowest nickel mass (…
Emission-Line Datacubes of the HH 32 Stellar Jet
Patrick Hartigan, Lynne Hillenbrand, Matuesz Matuszewski +5
We analyze datacubes of over 60 emission lines in the HH 32 stellar jet acquired with the Keck Cosmic Web Imager (KCWI). The data cover the less-explored blue portion of the spectr…
SN 2018fif: The Explosion of a Large Red Supergiant Discovered in Its Infancy by the Zwicky Transient Facility
Maayane T. Soumagnac, Noam Ganot, Ido Irani +32
High cadence transient surveys are able to capture supernovae closer to their first light than before. Applying analytical models to such early emission, we can constrain the proge…
iPTF 16hgs: A double-peaked Ca-rich gap transient in a metal poor, star forming dwarf galaxy
Kishalay De, Mansi M. Kasliwal, Therese Cantwell +18
Calcium rich gap transients represent an intriguing new class of faint and fast evolving supernovae that exhibit strong [Ca II] emission in their nebular phase spectra. In this pap…
iPTF16fnl: a faint and fast tidal disruption event in an E+A galaxy
N. Blagorodnova, S. Gezari, T. Hung +30
We present ground-based and \textit{Swift} observations of iPTF16fnl, a likely tidal disruption event (TDE) discovered by the intermediate Palomar Transient Factory (iPTF) survey a…
A Hubble Space Telescope Survey for Novae in M87. II. Snuffing out the Maximum Magnitude - Rate of Decline Relation for Novae as a Non-Standard Candle, and a Prediction of the Existence of Ultrafast Novae
Michael M. Shara, Trisha Doyle, Tod R. Lauer +9
The extensive grid of numerical simulations of nova eruptions of Yaron et al.(2005) first predicted that some classical novae might deviate significantly from the Maximum Magnitude…
iPTF16geu: A multiply imaged, gravitationally lensed type Ia supernova
A. Goobar, R. Amanullah, S. R. Kulkarni +31
We report the discovery of a multiply-imaged gravitationally lensed Type Ia supernova, iPTF16geu (SN 2016geu), at redshift . This phenomenon could be identified because th…
The GALEX Time Domain Survey. II. Wavelength-Dependent Variability of Active Galactic Nuclei in the Pan-STARRS1 Medium Deep Survey
T. Hung, S. Gezari, D. O. Jones +12
We analyze the wavelength-dependent variability of a sample of spectroscopically confirmed active galactic nuclei (AGN) selected from near-UV () variable sources in the GALEX…
A Hubble Space Telescope Survey for Novae in M87. I. Light and Color Curves, Spatial Distributions and the Nova Rate
Michael M. Shara, Trisha F. Doyle, Tod R. Lauer +6
The Hubble Space Telescope has imaged the central part of M87 over a 10 week span, leading to the discovery of 32 classical novae and nine fainter, likely very slow and/or symbioti…
The Arecibo Fast Radio Burst: Dense Circum-burst Medium
S. R. Kulkarni, E. O. Ofek, J. D. Neill
The nature of fast radio bursts (FRB) has been extensively debated. Here we investigate FRB121102, detected at Arecibo telescope and remarkable for its unusually large spectral ind…
Exploring the Role of Globular Cluster Specific Frequency on the Nova Rates in Three Virgo Elliptical Galaxies
C. Curtin, A. W. Shafter, C. J. Pritchet +3
It has been proposed that a galaxy's nova rate might be enhanced by the production of nova progenitor binaries in the dense cores of its globular clusters (GCs). To explore this id…
The influence of galaxy surface brightness on the mass-metallicity relation
Po-Feng Wu, Rolf-Peter Kudritzki, R. Brent Tully +1
We study the effect of surface brightness on the mass-metallicity relation using nearby galaxies whose gas content and metallicity profiles are available. Previous studies using fi…
