Identification of Extended Emission Gamma-Ray-Bursts Candidates using Machine Learning
K. Garcia-Cifuentes, R. L. Becerra, F. De Colle +2
Gamma-Ray bursts (GRBs) have been traditionally classified based on their duration. The increasing number of extended emission (EE) GRBs, lasting typically more than 2 seconds but…
Improving sampling and calibration of GRBs as distance indicators
Ariadna Montiel, J. I. Cabrera, Juan Carlos Hidalgo
We present a sample of 74 Gamma-Ray Bursts (GRBs) from the Fermi-GBM catalogue for which we compute the distance moduli and use them to constrain effective dark energy models. To o…
Optical polarimetric and multiwavelength flaring activity of blazar 3C279
N. Fraija, E. Benítez, D. Hiriart +5
An exhaustive analysis of 9-year optical R-band photopolarimetric data of the flat-spectrum radio quasar 3C279 from 2008 February 27 to 2017 May 25 is presented, alongside with mul…
An eclipsing binary black hole candidate system in the blazar Mrk 421
E. Benitez, J. I. Cabrera, N. Fraija +4
Removing outbursts from multiwavelength light curves of the blazar Mrk~421, we construct outburstless time series for this system. A model-independent power spectrum light curve an…
Flaring activity of Mrk 421 in 2012 and 2013: orphan flare and multiwavelength analysis
Nissim Fraija, José Ignacio Cabrera, Erika Benítez +1
The first one started in 2012 July 16 (MJD 56124) and the second one in 2013 April 9 (MJD 56391). The multiwavelength data analysis shows that the -ray flare observed in 2012 wa…
Rotation of the optical polarization angle associated with the 2008 γ-ray flare of blazar w comae
Marco Sorcia, Erika Benítez, David Hiriart +3
An --band photopolarimetric variability analysis of the TeV bright blazar W Comae, between 2008 February 28 and 2013 May 17, is presented. The source showed a gradual tendency t…
