The Spectral Energy Distribution of Fermi bright blazars

A. A. Abdo, M. Ackermann, M. Ajello +107

(Abridged) We have conducted a detailed investigation of the broad-band spectral properties of the γ-ray selected blazars of the Fermi LAT Bright AGN Sample (LBAS). By combining ou…

Mass Varying Neutrinos, Quintessence, and the Accelerating Expansion of the Universe

G. Y. Chitov, T. August, A. Natarajan +1

We analyze the Mass Varying Neutrino (MaVaN) scenario. We consider a minimal model of massless Dirac fermions coupled to a scalar field, mainly in the framework of finite temperatu…

The GASP-WEBT monitoring of 3C 454.3 during the 2008 optical-to-radio and gamma-ray outburst

M. Villata, C. M. Raiteri, M. A. Gurwell +6

Since 2001, the radio quasar 3C 454.3 has undergone a period of high optical activity, culminating in the brightest optical state ever observed, during the 2004-2005 outburst. The…

Phase Transition Generated Cosmological Magnetic Field at Large Scales

Tina Kahniashvili, Alexander G. Tevzadze, Bharat Ratra

We constrain a primordial magnetic field (PMF) generated during a phase transition (PT) using the big bang nucleosynthesis bound on the relativistic energy density. The amplitude o…

Constraints on dark energy from the lookback time versus redshift test

Lado Samushia, Abha Dev, Deepak Jain +1

We use lookback time versus redshift data from galaxy clusters (Capozziello et al., 2004) and passively evolving galaxies (Simon et al., 2005), and apply a bayesian prior on the to…

The correlated optical and radio variability of BL Lacertae. WEBT data analysis 1994-2005

M. Villata, C. M. Raiteri, V. M. Larionov +2

Since 1997, BL Lacertae has undergone a phase of high optical activity, with the occurrence of several prominent outbursts. Starting from 1999, the Whole Earth Blazar Telescope (WE…

Constraining dark energy with gamma-ray bursts

Lado Samushia, Bharat Ratra

We use the measurement of gamma-ray burst (GRB) distances to constrain dark energy cosmological model parameters. We employ two methods for analyzing GRB data - fitting luminosity…

Gravitational Radiation Generated by Cosmological Phase Transition Magnetic Fields

Tina Kahniashvili, Leonard Kisslinger, Trevor Stevens

We study gravitational waves generated by the cosmological magnetic fields induced via bubble collisions during the electroweak (EW) and QCD phase transitions. The magnetic field g…
