Polarimetry of the superluminous supernova LSQ14mo: no evidence for significant deviations from spherical symmetry
Giorgos Leloudas, Ferdinando Patat, Justyn R. Maund +10
We present the first polarimetric observations of a Type I superluminous supernova (SLSN). LSQ14mo was observed with VLT/FORS2 at five different epochs in the V band, with the obse…
The evolution of neutral gas in damped Lyman systems from the XQ-100 survey
R. Sánchez-Ramírez, S. L. Ellison, J. X. Prochaska +10
We present a sample of 38 intervening Damped Lyman (DLA) systems identified towards 100 quasars, observed during the XQ-100 survey. The XQ-100 DLA sample is combined wi…
The optical identifcation of events with poorly defined locations: The case of the Fermi GBM GRB140801A
V. M. Lipunov, J. Gorosabel, M. V. Pruzhinskaya +50
We report the early discovery of the optical afterglow of gamma-ray burst (GRB) 140801A in the 137 deg 3- error-box of the Fermi Gamma-ray Burst Monitor (GBM). MASTER is the…
The central engine of GRB 130831A and the energy breakdown of a relativistic explosion
M. De Pasquale, S. R. Oates, J. L. Racusin +37
Gamma-ray bursts (GRBs) are the most luminous explosions in the universe, yet the nature and physical properties of their energy sources are far from understood. Very important clu…
Limits on optical polarization during the prompt phase of GRB 140430A
D. Kopac, C. G. Mundell, J. Japelj +17
Gamma-ray burst GRB 140430A was detected by the Swift satellite and observed promptly with the imaging polarimeter RINGO3 mounted on the Liverpool Telescope, with observations begi…
Exploring the canonical behaviour of long gamma-ray bursts using an intrinsic multi-wavelength afterglow correlation
S. R. Oates, J. L. Racusin, M. De Pasquale +6
In this paper we further investigate the relationship, reported by Oates et al., 2012, between the optical/UV afterglow luminosity (measured at restframe 200s) and average afterglo…
Early optical follow-up of the nearby active star DG CVn during its 2014 superflare
M. D. Caballero-Garcia, V. Simon, M. Jelinek +20
DG CVn is a binary system in which one of the components is an M type dwarf ultra fast rotator, only three of which are known in the solar neighborhood. Observations of DG CVn by t…
The Spanish Square Kilometre Array White Book
J. A. Acosta-Pulido, I. Agudo, A. Alberdi +116
The Square Kilometre Array (SKA) is called to revolutionise essentially all areas of Astrophysics. With a collecting area of about a square kilometre, the SKA will be a transformat…
GRB 140606B / iPTF14bfu: Detection of shock-breakout emission from a cosmological gamma-ray burst?
Z. Cano, A. de Ugarte Postigo, D. Perley +13
We present optical and near-infrared photometry of GRB~140606B (), and optical photometry and spectroscopy of its associated supernova (SN). The results of our modelling i…
The high-redshift gamma-ray burst GRB140515A
A. Melandri, M. G. Bernardini, P. D'Avanzo +22
High-redshift gamma-ray bursts have several advantages for the study of the distant universe, providing unique information about the structure and properties of the galaxies in whi…
The Swift Gamma-Ray Burst Host Galaxy Legacy Survey - I. Sample Selection and Redshift Distribution
D. A. Perley, T. Krühler, S. Schulze +20
We introduce the Swift Gamma-Ray Burst Host Galaxy Legacy Survey ("SHOALS"), a multi-observatory high-redshift galaxy survey targeting the largest unbiased sample of long-duration…
Diversity in extinction laws of Type Ia supernovae measured between and
R. Amanullah, J. Johansson, A. Goobar +36
We present ultraviolet (UV) observations of six nearby Type~Ia supernovae (SNe~Ia) obtained with the Hubble Space Telescope, three of which were also observed in the near-IR (NIR)…
The Optically Unbiased Gamma-Ray Burst Host (TOUGH) Survey. VII. The Host Galaxy Luminosity Function: Probing the Relationship Between GRBs and Star Formation to Redshift
S. Schulze, R. Chapman, J. Hjorth +12
Gamma-ray bursts (GRBs) offer a route to characterizing star-forming galaxies and quantifying high- star formation that is distinct from the approach of traditional galaxy surve…
Necessary and sufficient conditions for macroscopic realism from quantum mechanics
Lucas Clemente, Johannes Kofler
Macroscopic realism, the classical world view that macroscopic objects exist independently of and are not influenced by measurements, is usually tested using Leggett-Garg inequalit…
