Variability-selected Active Galactic Nuclei in the VST-SUDARE/VOICE Survey of the COSMOS Field
D. De Cicco, M. Paolillo, G. Covone +16
Optical variability has proven to be an effective way of detecting AGNs in imaging surveys, lasting from weeks to years. In the present work we test its use as a tool to identify A…
PESSTO : survey description and products from the first data release by the Public ESO Spectroscopic Survey of Transient Objects
S. J. Smartt, S. Valenti, M. Fraser +99
The Public European Southern Observatory Spectroscopic Survey of Transient Objects (PESSTO) began as a public spectroscopic survey in April 2012. We describe the data reduction str…
Supersolar Ni/Fe production in the Type IIP SN 2012ec
Anders Jerkstrand, Stephen J. Smartt, Jesper Sollerman +14
SN 2012ec is a Type IIP supernova (SN) with a progenitor detection and comprehensive photospheric-phase observational coverage. Here, we present Very Large Telescope and PESSTO obs…
SN 2012ec: mass of the progenitor from PESSTO follow-up of the photospheric phase
C. Barbarino, M. Dall'Ora, M. T. Botticella +32
We present the results of a photometric and spectroscopic monitoring campaign of SN 2012ec, which exploded in the spiral galaxy NGC 1084, during the photospheric phase. The photome…
The Type IIP Supernova 2012aw in M95: hydrodynamical modelling of the photospheric phase from accurate spectrophotometric monitoring
M. Dall'Ora, M. T. Botticella, M. L. Pumo +38
We present an extensive optical and near-infrared photometric and spectroscopic campaign of the type IIP supernova SN 2012aw. The dataset densely covers the evolution of SN 2012aw…
Selecting superluminous supernovae in faint galaxies from the first year of the Pan-STARRS1 Medium Deep Survey
M. McCrum, S. J. Smartt, A. Rest +36
The Pan-STARRS1 (PS1) survey has obtained imaging in 5 bands (grizy_P1) over 10 Medium Deep Survey (MDS) fields covering a total of 70 square degrees. This paper describes the sear…
