Spectroscopic distance, mass, and age estimations for APOGEE DR17
Alexander Stone-Martinez, Jon A. Holtzman, Julie Imig +3
We derive distances and masses of stars from the Sloan Digital Sky Survey (SDSS) Apache Point Observatory Galactic Evolution Experiment (APOGEE) Data Release 17 (DR17) using simple…
Strong Carbon Features and a Red Early Color in the Underluminous Type Ia SN 2022xkq
Jeniveve Pearson, David J. Sand, Peter Lundqvist +85
We present optical, infrared, ultraviolet, and radio observations of SN 2022xkq, an underluminous fast-declining type Ia supernova (SN Ia) in NGC 1784 ( Mpc),…
Characterizing the Rapid Hydrogen Disappearance in SN2022crv: Evidence of a Continuum between Type Ib and IIb Supernova Properties
Yize Dong, Stefano Valenti, Chris Ashall +52
We present optical and near-infrared observations of SN~2022crv, a stripped envelope supernova in NGC~3054, discovered within 12 hrs of explosion by the Distance Less Than 40 Mpc S…
Profound optical flares from the relativistic jets of active galactic nuclei
Gopal Bhatta, Staszek Zola, M. Drozdz +11
Intense outbursts in blazars are among the most extreme phenomena seen in extragalactic objects. Studying these events can offer important information about the energetic physical…
A comprehensive optical search for pre-explosion outbursts from the quiescent progenitor of SN~2023ixf
Yize Dong, David J. Sand, Stefano Valenti +13
We perform a comprehensive search for optical precursor emission at the position of SN~2023ixf using data from the DLT40, ZTF and ATLAS surveys. By comparing the current data set w…
Early Spectroscopy and Dense Circumstellar Medium Interaction in SN 2023ixf
K. Azalee Bostroem, Jeniveve Pearson, Manisha Shrestha +53
We present the optical spectroscopic evolution of SN~2023ixf seen in sub-night cadence spectra from 1.18 to 14 days after explosion. We identify high-ionization emission features,…
