X-ray SN2014C obs. & CSM interaction in SNe
We present the results from our 7yr long broadband X-ray observing campaign of SN 2014C with Chandra and NuSTAR. These coordinated observations represent the first look at the... -
ZTF DR1 light curves of SNe Type Ia
Type Ia supernovae (SNe Ia) in the nearby Hubble flow are excellent distance indicators in cosmology. The Zwicky Transient Facility (ZTF) has observed a large sample of SNe from... -
Variable sources from HST in the JWST NEP TDF
The James Webb Space Telescope (JWST) North Ecliptic Pole (NEP) Time-domain Field (TDF) is a >14' diameter field optimized for multiwavelength time-domain science with JWST.... -
SN 2018jmt and SN 2019cj opt and NIR obs. mag.
We present optical and near-infrared observations of two Type Ibn supernovae (SNe), SN 2018jmt and SN 2019cj. Their light curves have rise times of about 10 days, reaching an... -
SN 2021wuf light curves
In this paper, we present an extensive analysis of SN 2021 wuf, a transition between Ia-norm and SN 1991T-like supernovae, which exploded at the periphery of the tidal bridge... -
UV & opt. phot. & spectra of Type Ia SN2011aa
We present optical observations and Monte Carlo radiative transfer modeling of the Type Ia supernova (SN Ia) SN 2011aa. With a {Delta}m_15_(B) of 0.59+/-0.07mag and a peak... -
Radio flux measurements of type Ib/c & II SNe
We assemble a large set of 2-10GHz radio flux density measurements and upper limits of 294 different supernovae (SNe), from the literature and our own and archival data. Only... -
The Pantheon+ analysis: cosmological constraints
We present constraints on cosmological parameters from the Pantheon+ analysis of 1701 light curves of 1550 distinct Type Ia supernovae (SNeIa) ranging in redshift from z=0.001... -
SNe Ia type LF study
We construct the Type Ia supernovae (SNe Ia) luminosity function (LF) using the Zwicky Transient Facility Bright Transient Survey (BTS) catalogue. While this magnitude-limited... -
Type Ia SN 2012ij opt. & NIR spectra
In this paper, we present photometric and spectroscopic observations of the subluminous Type Ia supernova (SNIa) 2012ij, which has an absolute B-band peak magnitude... -
Multiepoch opt. obs. of 91T/99aa-like SNe Ia
We present the photometry of 16 91T/99aa-like Type Ia Supernovae (SNeIa) observed by the Las Cumbres Observatory. We also use an additional set of 21 91T/99aa-like SNe Ia and 87... -
SN 2009nr UBVRI light curves
We present the results of our UBVRI CCD photometry for the second brightest supernova of 2009, SN 2009nr, discovered during a sky survey with the telescopes of the MASTER... -
BVRI light curves of SN 2007gi
We present optical photometry and spectra for the Type Ia supernova (SN Ia) 2007gi in the nearby galaxy NGC 4036. SN 2007gi is characterized by extremely high-velocity (HV)... -
Classifications of SN host galaxies. III
A homogeneous sample comprising host galaxies of 604 recent supernovae, including 212 objects discovered primarily in 2003 and 2004, has been classified on the David Dunlap... -
Classifications of SN host galaxies
Classifications on the DDO system are given for an additional 231 host galaxies of supernovae that have been discovered during the course of the Lick Observatory Supernova... -
Supernovae host galaxies classification
Classifications on the DDO system are given for the host galaxies of 177 supernovae (SNe) that have been discovered since 1997 during the course of the Lick Observatory... -
Sgr A East SNR multiwavelength images
Dust formation in supernova ejecta is currently the leading candidate to explain the large quantities of dust observed in the distant, early universe. However, it is unclear... -
Supernova host galaxies in SDSS-IV MaNGA
We crossmatch galaxies from Mapping Nearby Galaxies at Apache Point Observatory with the Open Supernova Catalog, obtaining a total of 132 SNe within MaNGA bundle. These 132 SNe... -
UBVRI light curves of SN 2011dh
CCD UBVRI photometry is presented for type IIb SN 2011dh for about 300 days. The main photometric parameters are derived and the comparison with SNe of similar types is... -
SN 2004dj UBVRI light curves
CCD UBVRI photometry is presented for type II SN 2004dj for about 1200 days, starting on day 2 past discovery. The photometric behaviour is typical of SNe II-P, although some...
