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…
