Simultaneous multiwavelength observations of V404 Cygni during its 2015 June outburst decay strengthen the case for an extremely energetic jet-base
Dipankar Maitra, John F. Scarpaci, Victoria Grinberg +4
We present results of multiband optical photometry of the black hole X-ray binary system V404 Cygni obtained using Wheaton College Observatory's 0.3m telescope, along with strictly…
An elevation of 0.1 light-seconds for the optical jet base in an accreting Galactic black hole system
Poshak Gandhi, Matteo Bachetti, Vik S. Dhillon +25
Relativistic plasma jets are observed in many accreting black holes. According to theory, coiled magnetic fields close to the black hole accelerate and collimate the plasma, leadin…
A new method for extending solutions to the self-similar relativistic magnetohydrodynamics equations for black hole outflows
Chiara Ceccobello, Yuri Cavecchi, Martin H. M. Heemskerk +3
The paradigm in which magnetic fields play a crucial role in launching/collimating outflows in many astrophysical objects continues to gain support. However, semi-analytical models…
Paving the way to simultaneous multi-wavelength astronomy
M. J. Middleton, P. Casella, P. Gandhi +49
Whilst astronomy as a science is historically founded on observations at optical wavelengths, studying the Universe in other bands has yielded remarkable discoveries, from pulsars…
Single-dish and VLBI observations of Cygnus X-3 during the 2016 giant flare episode
E. Egron, A. Pellizzoni, M. Giroletti +34
In September 2016, the microquasar Cygnus X-3 underwent a giant radio flare, which was monitored for 6 days with the Medicina Radio Astronomical Station and the Sardinia Radio Tele…
Simultaneous Monitoring of X-ray and Radio Variability in Sagittarius A*
Daniel M. Capellupo, Daryl Haggard, Nicolas Choux +14
Monitoring of Sagittarius A* from X-ray to radio wavelengths has revealed structured variability --- including X-ray flares --- but it is challenging to establish correlations betw…
