Multiwavelength survey of a sample of flat-spectrum radio-loud narrow-line Seyfert 1 galaxies

L. Foschini, M. Berton, A. Caccianiga +27

We report on a multiwavelength survey of a sample of 42 flat-spectrum radio-loud narrow-line Seyfert 1 galaxies (RLNLS1s). This is the largest known sample of this type of active g…

Volcanoes muon imaging using Cherenkov telescopes

Osvaldo Catalano, Melania Del Santo, Teresa Mineo +3

A detailed understanding of a volcano inner structure is one of the key-points for the volcanic hazards evaluation. To this aim, in the last decade, geophysical radiography techniq…

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…

A test of the nature of the Fe K Line in the neutron star low-mass X-ray binary Serpens X-1

Chia-Ying Chiang, Edward M. Cackett, Jon M. Miller +12

Broad Fe K emission lines have been widely observed in the X-ray spectra of black hole systems, and in neutron star systems as well. The intrinsically narrow Fe K fluorescent line…

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…

A search for Galactic transients disguised as gamma-ray bursts

A. Clerici, C. Guidorzi, V. La Parola

A significant fraction of cosmological gamma-ray bursts (GRBs) are characterised by a fast rise and exponential decay (FRED) temporal structure. This is not a distinctive feature o…

Energy Estimation of Cosmic Rays with the Engineering Radio Array of the Pierre Auger Observatory

The Pierre Auger Collaboration, Alexander Aab, Pedro Abreu +448

The Auger Engineering Radio Array (AERA) is part of the Pierre Auger Observatory and is used to detect the radio emission of cosmic-ray air showers. These observations are compared…

The radio/X-ray correlation in Cyg X-3 and the nature of its hard spectral state

Andrzej A. Zdziarski, Alberto Segreto, Guy G. Pooley

We study the radio/X-ray correlation in Cyg X-3. It has been known that the soft and hard X-ray fluxes in the hard spectral state are correlated positively and negatively, respecti…

Swift J1734.5-3027: a new long type-I X-ray bursting source

E. Bozzo, P. Romano, M. Falanga +3

Swift J1734.5-3027 is a hard X-ray transient discovered by Swift while undergoing an outburst in September 2013. Archival observations showed that this source underwent a previous…

An improved limit to the diffuse flux of ultra-high energy neutrinos from the Pierre Auger Observatory

The Pierre Auger Collaboration, Alexander Aab, Pedro Abreu +462

Neutrinos in the cosmic ray flux with energies near 1 EeV and above are detectable with the Surface Detector array of the Pierre Auger Observatory. We report here on searches throu…

The Swift-UVOT ultraviolet and visible grism calibration

N. P. M. Kuin, W. Landsman, A. A. Breeveld +16

We present the calibration of the Swift UVOT grisms, of which there are two, providing low-resolution field spectroscopy in the ultraviolet and optical bands respectively. The UV g…

Giant outburst from the supergiant fast X-ray transient IGR J17544-2619: accretion from a transient disc?

P. Romano, E. Bozzo, V. Mangano +7

Supergiant fast X-ray transients (SFXTs) are high mass X-ray binaries associated with OB supergiant companions and characterised by an X-ray flaring behaviour whose dynamical range…
