Assigning degrees of stochasticity to blazar light curves in the radio band using complex networks
(MDPI, 2022)
We focus on characterizing the high-energy emission mechanisms of blazars by analyzing
the variability in the radio band of the light curves of more than a thousand sources. We are interested
in assigning complexity ...
Radio Variability in Seyfert Nuclei
(2009)
Comparison of 8.4-GHz radio images of a sample of 11 early-type Seyfert galaxies with previous observations reveals possible variation in the nuclear radio flux density in 5 of them over a 7-yr period. We find no correlation ...
The nature of supernovae 2010O and 2010P in Arp 299-II. Radio emission
(OXFORD UNIV PRESS, 2014)
We report radio observations of two stripped-envelope supernovae (SNe), 2010O and 2010P, which exploded within a few days of each other in the luminous infrared galaxy Arp 299. Whilst SN 2010O remains undetected at radio ...
The He-Rich Core-Collapse Supernova 2007Y: Observations from X-Ray to Radio Wavelengths
(2009)
A detailed study spanning approximately a year has been conducted on the Type Ib supernova 2007Y. Imaging was obtained from X-ray to radio wavelengths, and a comprehensive set of multi-band (w2m2w1u'g'r'i'UBVYJHKs) light ...
Multiwavelength variability power spectrum analysis of the blazars 3C 279 and PKS 1510–089 on multiple timescales
(IOP, 2022)
We present the results of variability power spectral density (PSD) analysis using multiwavelength radio to GeV gamma-ray light curves covering timescales of decades/years to days/minutes for the blazars 3C 279 and PKS ...
Patterns in the Multiwavelength Behavior of Candidate Neutrino Blazars
(IOP Publishing, 2020)
Motivated by the identification of the blazar TXS 0506+056 as the first promising high-energy neutrino counterpart candidate, we search for additional neutrino blazar candidates among the Fermi-Large Area Telescope detected ...
The nature of supernovae 2010O and 2010P in Arp 299-I. Near-infrared and optical evolution
(OXFORD UNIV PRESS, 2014)
We present near-infrared and optical photometry, plus optical spectroscopy of two stripped-envelope supernovae (SNe) 2010O and 2010P that exploded in two different components of an interacting luminous infrared galaxy Arp ...
