We present photometry and spectroscopy of nine Type II-P/L supernovae (SNe) with redshifts in the 0.045~<z~<0.335 range, with a view to re-examining their utility as...

The progenitors of astronomical transients are linked to a specific stellar population and galactic environment, and observing their host galaxies hence constrains the physical...

The first phase of the Carnegie Supernova Project (CSP-I) was a dedicated supernova follow-up program based at the Las Campanas Observatory that collected science data of young,...

We study PTF11mnb, a He-poor supernova (SN) whose light curves resemble those of SN 2005bf, a peculiar double-peaked stripped-envelope (SE) SN, until the declining phase after...

We present optical photometry of Type IIn SN iPTF13z, obtained by the intermediate Palomar Transient Factory (iPTF) collaboration using the 1.2m Samuel Oschin telescope and the...

Mass loss processes are a key uncertainty in the evolution of massive stars. They determine the amount of mass and angular momentum retained by the star, thus influencing its...

Type Ibn supernovae (SNe Ibn) are thought to be the core-collapse explosions of massive stars whose ejecta interact with He-rich circumstellar material (CSM). We report the...

We investigate two stripped-envelope supernovae (SNe) discovered in the nearby galaxy NGC 5806 by the (i)PTF. We classify PTF12os as a Type IIb SN based on our spectral...

Temporal variability of narrow absorption lines in high-resolution spectra of Type Ia supernovae (SNe Ia) is studied to search for circumstellar matter. Time series which...

Spectral modelling of typeII supernova atmospheres indicates a clear dependence of metal line strengths on progenitor metallicity. This dependence motivates further work to...

Type IIP supernovae (SNe IIP) have recently been proposed as metallicity (Z) probes. The spectral models of Dessart et al. (2014MNRAS.440.1856D) showed that the...

We present optical and near-infrared (NIR) photometry and spectroscopy as well as modelling of the lightcurves of the Type IIb supernova (SN) 2011dh. Our extensive dataset, for...

The Public European Southern Observatory Spectroscopic Survey of Transient Objects (PESSTO) began as a public spectroscopic survey in April 2012. PESSTO classifies transients...

We present optical (ugriz) light curve templates of supernovae Ib/c from the SDSS II SN survey. Cone search capability for table J/A+A/574/A60/table1 (SDSS sample of 20 SNe Ib,...

We present optical and near-infrared (NIR) photometry for three gamma-ray burst supernovae (GRB-SNe): GRB 120729A, GRB 130215A/SN 2013ez and GRB 130831A/SN 2013fu. For GRB...

We present optical and near-infrared (NIR) photometry and spectroscopy of the Type IIb supernova (SN) 2011dh for the first 100 days. We complement our extensive dataset with...

We present optical (uBgVri) and near-infrared (YJHKs) photometry of Type IIn Supernovae 2005kj, 2006aa, 2006bo, 2006qq, 2008fq, obtained by the Carnege Supernova Project. We...

We present 32 epochs of optical (3300-9700{AA}) spectrophotometric observations of the nearby quintessential "normal" type Ia supernova (SN Ia) SN 2011fe in the galaxy M101,...

We present a joined photometric calibration for the SNLS and the SDSS supernova surveys. Our main delivery are catalogs of natural AB magnitudes for a large set of selected...

Supernova 1987A (SN 1987A) in the neighbouring Large Magellanic Cloud offers a superb opportunity to follow the evolution of a supernova and its remnant in unprecedented detail....
