The unusual multiwavelength properties of the gamma-ray source PMNJ1603-4904

Cornelia Müller, M. Kadler, R. Ojha +27

We investigate the nature and classification of PMNJ1603-4904, a bright radio source close to the Galactic plane, which is associated with one of the brightest hard-spectrum gamma-…

High Density Circumstellar Interaction in the Luminous Type IIn SN 2010jl: The first 1100 days

Claes Fransson, Mattias Ergon, Peter J. Challis +16

HST and ground based observations of the Type IIn SN 2010jl are analyzed, including photometry, spectroscopy in the ultraviolet, optical and NIR bands, 26-1128 days after first det…

Multi-Wavelength Observations of PKS 2142-75 during Active and Quiescent Gamma-Ray States

Michael Dutka, Roopesh Ojha, Katja Pottschmidt +13

PKS2142-75 (a.k.a. 2FGL J2147.4-7534) is a flat-spectrum radio quasar that was observed quasi-simultaneously by a suite of instruments across the elec- tromagnetic spectrum during…

Spatial distributions of core-collapse supernovae in infrared-bright galaxies

Tuomas Kangas, Seppo Mattila, Erkki Kankare +4

We have measured the correlation between the locations of core-collapse supernovae (CCSNe) and host galaxy light in the Ha line, near ultraviolet (NUV), R-band and Ks-band to const…

An active state of the BL Lac Object Markarian 421 detected by INTEGRAL in April 2013

E. Pian, M. Tuerler, M. Fiocchi +22

Multiwavelength variability of blazars offers indirect insight into their powerful engines and on the mechanisms through which energy is propagated from the centre down the jet. Th…

Near infrared and gamma-ray monitoring of TANAMI gamma-ray bright sources

R. Nesci, G. Tosti, T. Pursimo +2

Spectral energy distribution and its variability are basic tools for understanding the physical processes operating in active galactic nuclei (AGN). In this paper we report the res…

Super Luminous Ic Supernovae: catching a magnetar by the tail

C. Inserra, S. J. Smartt, A. Jerkstrand +37

We report extensive observational data for five of the lowest redshift Super-Luminous Type Ic Supernovae (SL-SNe Ic) discovered to date, namely PTF10hgi, SN2011ke, PTF11rks, SN2011…

Discovery of the broad-lined Type Ic SN 2013cq associated with the very energetic GRB 130427A

D. Xu, A. de Ugarte Postigo, G. Leloudas +25

Long-duration gamma-ray bursts (GRBs) at z < 1 are in most cases found to be accompanied by bright, broad-lined Type Ic supernovae (SNe Ic-BL). The highest-energy GRBs are mostly l…
