The Close AGN Reference Survey (CARS): Mrk 1018 halts dimming and experiences strong short-term variability
M. Krumpe, B. Husemann, G. R. Tremblay +12
After changing optical AGN type from 1.9 to 1 in 1984, the AGN Mrk 1018 recently reverted back to its type 1.9 state. Our ongoing monitoring now reveals that the AGN has halted its…
The wind and the magnetospheric accretion onto the T Tauri star S Coronae Australis at sub-au resolution
R. Garcia Lopez, K. Perraut, A. Caratti o Garatti +70
To investigate the inner regions of protoplanetary disks, we performed near-infrared interferometric observations of the classical TTauri binary system S CrA. We present the first…
Twelve years of spectroscopic monitoring in the Galactic Center: the closest look at S-stars near the black hole
M. Habibi, S. Gillessen, F. Martins +11
We study the young S-stars within a distance of 0.04 pc from the supermassive black hole in the center of our Galaxy. Given how inhospitable the region is for star formation, their…
Locating the intense interstellar scattering towards the inner Galaxy
J. Dexter, A. Deller, G. C. Bower +9
We use VLBA+VLA observations to measure the sizes of the scatter-broadened images of 6 of the most heavily scattered known pulsars: 3 within the Galactic Centre (GC) and 3 elsewher…
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…
Sagittarius A* High Energy X-ray Flare Properties During NuSTAR Monitoring of the Galactic Center from 2012 to 2015
Shuo Zhang, Frederick K. Baganoff, Gabriele Ponti +17
Understanding the origin of the flaring activity from the Galactic center supermassive black hole, Sagittarius A*, is a major scientific goal of the NuSTAR Galactic plane survey ca…
