A time-series VI study of the variable stars of the globular cluster NGC 6397
J. A. Ahumada, A. Arellano Ferro, I. Bustos Fierro +4
We present a new time-series VI CCD photometry of the globular cluster NGC 6397, from which we obtained and analysed the light curves of 35 variables carefully identified in the cl…
NGC 6712: the variable star population of a tidally disrupted globular cluster
D. Deras, A. Arellano Ferro, C. Lázaro +4
We present an analysis of CCD time series photometry of globular cluster NGC 6712. Our main goal is to study the variable star population as indicators of the cluster m…
Multiwavelength behaviour of the blazar 3C279: decade-long study from -ray to radio
V. M. Larionov, S. G. Jorstad, A. P. Marscher +84
We report the results of decade-long (2008-2018) -ray to 1 GHz radio monitoring of the blazar 3C 279, including GASP/WEBT, and data, as well as polarim…
A refined analysis of the low-mass eclipsing binary system T-Cyg1-12664
R. Ramón Iglesias-Marzoa, M. López-Morales, M. J. Arévalo +2
The observational mass-radius relation of main sequence stars with masses between ~0.3 and 1.0 Msun reveals deviations between the stellar radii predicted by models and the observe…
Synchrotron emission from the blazar PG 1553+113. An analysis of its flux and polarization variability
C. M. Raiteri, F. Nicastro, A. Stamerra +4
In 2015 July 29 - September 1 the satellite XMM-Newton pointed at the BL Lac object PG 1553+133 six times, collecting data for 218 hours. During one of these epochs, simultaneous o…
Exceptional outburst of the blazar CTA 102 in 2012: The GASP-WEBT campaign and its extension
V. M. Larionov, M. Villata, C. M. Raiteri +49
After several years of quiescence, the blazar CTA 102 underwent an exceptional outburst in 2012 September-October. The flare was tracked from gamma-ray to near-infrared frequencies…
The WEBT campaign on the BL Lac object PG 1553+113 in 2013. An analysis of the enigmatic synchrotron emission
C. M. Raiteri, A. Stamerra, M. Villata +2
A multifrequency campaign on the BL Lac object PG 1553+113 was organized by the Whole Earth Blazar Telescope (WEBT) in 2013 April-August, involving 19 optical, two near-IR, and thr…
Multiwavelength behaviour of the blazar OJ 248 from radio to γ-rays
M. I. Carnerero, C. M. Raiteri, M. Villata +4
We present an analysis of the multiwavelength behaviour of the blazar OJ 248 at z = 0.939 in the period 2006-2013. We use low-energy data (optical, near-infrared, and radio) obtain…
Infrared properties of blazars: putting the GASP-WEBT sources into context
C. M. Raiteri, M. Villata, M. I. Carnerero +16
The infrared properties of blazars can be studied from the statistical point of view with the help of sky surveys, like that provided by the Wide-field Infrared Survey Explorer (WI…
