Time evolution of magnetic activity cycles in young suns: The curious case of kappa Ceti
S. Boro Saikia, T. Lueftinger, C. P. Folsom +15
A detailed investigation of the magnetic properties of young Sun-like stars can provide valuable information on our Sun's magnetic past and its impact on the early Earth. We determ…
A Swift view of X-ray and UV radiation in the planet-forming T-Tauri system PDS 70
Simon Joyce, John Pye, Jonathan Nichols +4
PDS 70 is a 5 Myr old star with a gas and dust disc in which several proto-planets have been discovered. We present the first UV detection of the system along with X-ray obse…
Modelling the environment around five ultracool dwarfs via the radio domain
Y. T. Metodieva, A. A. Kuznetsov, A. E. Antonova +3
We present the results of a series of short radio observations of six ultracool dwarfs made using the upgraded VLA in S (2--4GHz) and C (4--7GHz) bands. LSR J1835+3259 exhibits a 1…
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…
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…
Low-resolution optical spectra of ultracool dwarfs with OSIRIS/GTC
Yanina Metodieva, Antoaneta Antonova, Valeri Golev +3
We present the results of low-resolution optical spectroscopy with OSIRIS/GTC (Optical System for Imaging and Low Resolution Integrated Spectroscopy / Gran Telescopio Canarias) for…
The awakening of BL Lacertae: observations by Fermi, Swift, and the GASP-WEBT
C. M. Raiteri, M. Villata, F. D'Ammando +4
Since the launch of the Fermi satellite, BL Lacertae has been moderately active at gamma-rays and optical frequencies until May 2011, when the source started a series of strong fla…
Volume-limited radio survey of ultracool dwarfs
A. Antonova, G. Hallinan, J. G. Doyle +5
We conducted a volume-limited survey at 4.9 GHz of 32 nearby ultracool dwarfs with spectral types covering the range M7 -- T8. A statistical analysis was performed on the combined…
