Young Supernova Experiment (YSE) DR1
We present the Young Supernova Experiment Data Release 1 (YSE DR1), comprised of processed multicolor PanSTARRS1 griz and Zwicky Transient Facility (ZTF) gr photometry of 1975... -
The PTF core-collapse SN host-galaxy sample. I.
Several thousand core-collapse supernovae (CCSNe) of different flavors have been discovered so far. However, identifying their progenitors has remained an outstanding open... -
Models and yields of 13-120M_{sun}_ massive stars
We present a new grid of presupernova models of massive stars extending in mass between 13 and 120M_{sun}, covering four metallicities (i.e., [Fe/H]=0, -1, -2, and -3) and three... -
SNe II light curves & spectra from the CfA
We present multiband photometry of 60 spectroscopically confirmed supernovae (SNe): 39 SNe II/IIP, 19 IIn, 1 IIb, and 1 that was originally classified as a IIn but later as a... -
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... -
Optical and near-IR light curves of 64 SNe
We present a densely sampled, homogeneous set of light curves of 64 low-redshift (z<~0.05) stripped-envelope supernovae (SNe of Type IIb, Ib, Ic, and Ic-BL). These data were... -
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... -
Light-curve parameters from the SNLS
We combine high-redshift Type Ia supernovae from the first three years of the Supernova Legacy Survey (SNLS) with other supernova (SN) samples, primarily at lower redshifts, to... -
First-year SDSS-II SN results
We present measurements of the Hubble diagram for 103 Type Ia supernovae (SNe) with redshifts 0.04<z<0.42, discovered during the first season (Fall 2005) of the Sloan... -
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... -
SN 2017egm spectroscopic & photometric obs.
When discovered, SN 2017egm was the closest (redshift z=0.03) hydrogen-poor superluminous supernova (SLSN-I) and a rare case that exploded in a massive and metal-rich galaxy.... -
Extragalactic fast blue optical transients from ZTF
We present a search for extragalactic fast blue optical transients (FBOTs) during Phase I of the Zwicky Transient Facility (ZTF). We identify 38 candidates with durations above... -
HST/WFC3 phot. of the S1-SX images of SN Refsdal
In late 2014, four images of supernova (SN) "Refsdal," the first known example of a strongly lensed SN with multiple resolved images, were detected in the MACS J1149...
