Photometric classification of QSOs from ALHAMBRA survey using random forest
Benjamin Arroquia-Cuadros, Nestor Sanchez, Vicent Gomez +3
Context: Given the current big data era in Astronomy, machine learning based methods have being applied over the last years to identify or classify objects like quasars, galaxies a…
Study of the open cluster Alessi-Teutsch 9 (ASCC 10) using multiband photometry and Gaia EDR3
Nestor Sanchez, Fatima Lopez-Martinez, Sandra Ocando +1
There is a growing interest in the automated characterization of open clusters using data from the Gaia mission. This work evidences the importance of choosing an appropriate sampl…
Advances in Understanding High-Mass X-ray Binaries with INTEGRAL and Future Directions
Peter Kretschmar, Felix Fürst, Lara Sidoli +48
High mass X-ray binaries are among the brightest X-ray sources in the Milky Way, as well as in nearby Galaxies. Thanks to their highly variable emissions and complex phenomenology,…
K2-280b -- a low density warm sub-Saturn around a mildly evolved star
Grzegorz Nowak, Enric Palle, Davide Gandolfi +57
We present an independent discovery and detailed characterisation of K2-280b, a transiting low density warm sub-Saturn in a 19.9-day moderately eccentric orbit (e = 0.35_{-0.04}^{+…
The 1989 and 2015 outbursts of V404 Cygni: a global study of wind-related optical features
D. Mata Sánchez, T. Muñoz-Darias, J. Casares +19
The black hole transient V404 Cygni exhibited a bright outburst in June 2015 that was intensively followed over a wide range of wavelengths. Our team obtained high time resolution…
Authenticating the Presence of a Relativistic Massive Black Hole Binary in OJ 287 Using its General Relativity Centenary Flare: Improved Orbital Parameters
Lankeswar Dey, M. J. Valtonen, A. Gopakumar +5
Results from regular monitoring of relativistic compact binaries like PSR 1913+16 are consistent with the dominant (quadrupole) order emission of gravitational waves (GWs). We show…
