OGLE-2013-BLG-0911Lb: A Secondary on the Brown-Dwarf Planet Boundary around an M-dwarf
Shota Miyazaki, Takahiro Sumi, David P. Bennett +92
We present the analysis of the binary-lens microlensing event OGLE-2013-BLG-0911. The best-fit solutions indicate the binary mass ratio of q~0.03 which differs from that reported i…
Simultaneous Millimeter-wave and X-ray monitoring of the Seyfert Galaxy NGC 7469
Ehud Behar, Shai Kaspi, Gabriel Paubert +6
We report on daily monitoring of the Seyfert galaxy NGC 7469, around 95 GHz and 143 GHz, with the IRAM 30 m radio telescope, and with the Swift X-Ray and UV/Optical telescopes, ove…
Incoherent fast variability of X-ray obscurers. The case of NGC 3783
B. De Marco, T. P. Adhikari, G. Ponti +22
Context. Obscuration events caused by outflowing clumps or streams of high column density, low ionisation gas, heavily absorbing the X-ray continuum, have been witnessed in a numbe…
Multi-wavelength campaign on NGC 7469 V. Analysis of the HST/COS observations: Super solar metallicity, distance, and trough variation models
N. Arav, X. Xu, G. A. Kriss +18
Aims. Our aim is to determine the distance of the UV outflow components from the central source, their abundances and total column density, and the mechanism responsible for their…
Four (Super)luminous Supernovae from the First Months of the ZTF Survey
R. Lunnan, Lin Yan, D. A. Perley +30
We present photometry and spectroscopy of four hydrogen-poor luminous supernovae discovered during the two-month science commissioning and early operations of the Zwicky Transient…
The trans-Neptunian object (84922) 2003 VS2 through stellar occultations
Gustavo Benedetti-Rossi, P. Santos-Sanz, J. L. Ortiz +50
We present results from three world-wide campaigns that resulted in the detections of two single-chord and one multi-chord stellar occultations by the Plutino object (84922) 2003~V…
