Si and Ca high-velocity features in SNe Ia
The high-velocity features (HVFs) in optical spectra of type Ia supernovae (SNe Ia) are examined with a large sample including very early-time spectra (e.g., t<-7days).... -
SNe Ia light curves for the LSQ-CSP sample
The La Silla/QUEST Variability Survey (LSQ) and the Carnegie Supernova Project (CSP II) are collaborating to discover and obtain photometric light curves for a large sample of... -
Presupernova evolution
We present a new set of zero metallicity models in the range 13-80M_{sun}_ together to the associated explosive nucleosynthesis. These models are fully homogeneous with the... -
Relativistic EOS for core-collapse SN simulations
We construct the equation of state (EOS) of dense matter covering a wide range of temperature, proton fraction, and density for the use of core-collapse supernova simulations.... -
Light curves for 165 SNe
We present BVRI light curves of 165 Type Ia supernovae (SNe Ia) from the Lick Observatory Supernova Search follow-up photometry program from 1998 through 2008. Our light curves... -
First-year SDSS-II SN results
We present measurements of the Hubble diagram for 103 Type Ia supernovae (SNe) with redshifts 0.04 -
Finding tidal disruption event & flares in ZTF
Transient accretion events onto supermassive black holes (SMBHs), such as tidal disruption events (TDEs), Bowen Fluorescence Flares (BFFs), and active galactic nuclei (AGNs),... -
Long-term sp. obs. of SN IIb/Ib 2022crv
We present optical, near-infrared, and radio observations of supernova (SN) SN IIb 2022crv. We show that it retained a very thin H envelope and transitioned from an SN IIb to an... -
TESS 4yrs obs. of Type Ia supernovae
We present 307 type Ia supernova (SN) light curves from the first 4yr of the Transiting Exoplanet Survey Satellite mission. We use this sample to characterize the shapes of the... -
The iron yield of core-collapse supernovae
We present a systematic analysis of 191 stripped-envelope supernovae (SE SNe), aimed at computing their 56Ni masses from the luminosity in their radioactive tails (M_Ni_^tail^)... -

We present an extensive, panchromatic photometric (UV, optical, and near-IR) and low-resolution optical spectroscopic coverage of a Type IIP supernova SN 2018gj that occurred on... -
SN2019wxt follow-up
We present optical, radio, and X-ray observations of a rapidly evolving transient SN2019wxt (PS19hgw), discovered during the search for an electromagnetic counterpart to the... -
SNII during ZTF 1st phase survey with follow-up sp.
Narrow transient emission lines (flash-ionization features) in early supernova (SN) spectra trace the presence of circumstellar material (CSM) around the massive progenitor... -
Opt. spectra of type Iax SN 2014dt over 500d
Type Iax supernovae (SNe Iax) are the largest known class of peculiar white dwarf SNe, distinct from normal Type Ia supernovae (SNe Ia). The unique properties of SNe Iax,... -
Type Ia SN2016ije photometry and sp. follow-up
We have conducted photometric and spectroscopic observations of the peculiar Type Ia supernova (SN Ia) 2016ije that was discovered through the Tsinghua-NAOC Transient Survey.... -
NIR and Optical LCs and spectra of Type Ic SN2021krf
We present near-infrared (NIR) and optical observations of the Type Ic supernova (SN Ic) SN 2021krf obtained between days 13 and 259 at several ground-based telescopes. The NIR... -
Spectroscopic analysis of ASAS-SN SNe Ia
We present a spectroscopic analysis of 44 low-luminosity host galaxies of Type Ia supernovae (SNe Ia) detected by the All-Sky Automated Survey for Supernovae (ASAS-SN), using... -
ugriBV phot. & spectra of type II-P SN2019mhm
We present pre- and postexplosion observations of the Type II-P supernova (SN II-P) 2019mhm located in NGC 6753. Based on optical spectroscopy and photometry, we show that SN... -
LCs and spectra of Type Ia SN 2021hpr
The progenitor system of Type Ia supernovae (SNe Ia) is expected to be a close binary system consisting of a carbon/oxygen white dwarf (WD) and a nondegenerate star or another...
