The THESEUS space mission concept: science case, design and expected performances
L. Amati, P. O'Brien, D. Goetz +208
THESEUS is a space mission concept aimed at exploiting Gamma-Ray Bursts for investigating the early Universe and at providing a substantial advancement of multi-messenger and time-…
First Results from the REAL-time Transient Acquisition backend (REALTA) at the Irish LOFAR station
P. C. Murphy, P. Callanan, J. McCauley +27
Modern radio interferometers such as the LOw Frequency ARray (LOFAR) are capable of producing data at hundreds of gigabits to terabits per second. This high data rate makes the ana…
Analysis of optical spectroscopy and photometry of the type I X-ray bursting system UW CrB
M. R. Kennedy, P. Callanan, P. M. Garnavich +19
UW Coronae Borealis (UW CrB) is a low mass X-ray binary that shows both Type 1 X-ray and optical bursts, which typically last for 20 s. The system has a binary period of close to 2…
The new eclipsing CV MASTER OTJ192328.22+612413.5 - a possible SW Sextantis Star
M. R. Kennedy, P. Callanan, P. M. Garnavich +7
We present optical photometry and spectroscopy of the new eclipsing Cataclysmic Variable MASTER OTJ192328.22+612413.5, discovered by the MASTER team. We find the orbital period to…
X-ray observations of FO Aqr during the 2016 low state
M. R. Kennedy, P. M. Garnavich, C. Littlefield +5
We present the first ever X-ray data taken of an intermediate polar, FO Aqr, when in a low accretion state and during the subsequent recovery. The Swift and Chandra X-ray data take…
Multi-wavelength Observations of the Binary System PSR B1259-63/LS~2883 around the 2014 Periastron Passage
M. Chernyakova, A. Neronov, B. van Soelen +16
We report on the results of the extensive multi-wavelength campaign from optical to GeV gamma-rays of the 2014 periastron passage of PSR B1259-63, which is a unique high-mass gamma…
Optical spectra of FO Aquarii during low and high accretion rates
M. R. Kennedy, P. M. Garnavich, C. Littlefield +7
Between May 2016 and September 2018, the intermediate polar (IP) FO Aquarii exhibited two distinct low states and one failed low state. We present optical spectroscopy of FO Aquari…
XMM-Newton Observations of the Peculiar Cataclysmic Variable Lanning 386: X-ray evidence for a Magnetic Primary
M. R. Kennedy, P. Callanan, P. M. Garnavich +2
We present the first X-ray observations of the eclipsing cataclysmic variables Lanning 386 and MASTER OTJ192328.22+612413.5, possible SW Sextantis systems. The X-ray light curve of…
Infrared Observations and Energetic Outburst of GRS 1915+105
S. Chaty, I. F. Mirabel, L. F. Rodriguez +4
Multiple near-infrared wavelengths observations, carried out since 1993 on the galactic superluminal source of relativistic ejections GRS 1915+105, have yielded three important res…
