Detection and characterization of an ultra-dense sub-Neptune planet orbiting the Sun-like star HD 119130
R. Luque, G. Nowak, E. Pallé +51
We present the discovery and characterization of a new transiting planet from Campaign 17 of the Kepler extended mission K2. HD 119130 b is a warm sub-Neptune on a 17-d orbit aroun…
Space Telescope and Optical Reverberation Mapping Project. X. Understanding the Absorption-Line Holiday in NGC 5548
M. Dehghanian, G. J. Ferland, G. A. Kriss +27
The flux variations in the emission lines in active galactic nuclei (AGNs) are driven by variations in the ionizing continuum flux --which are usually reflected in the observable U…
Evidence for massive warm-hot circumgalactic medium around NGC 3221
Sanskriti Das, Smita Mathur, Anjali Gupta +3
We report a 3.4 detection of the warm-hot, massive, extended circumgalactic medium (CGM) around an L star-forming spiral galaxy NGC 3221, using deep Suzaku observations.…
A High Signal-to-Noise HST Spectrum Toward J1009+0713: Precise Absorption Measurements in the CGM of Two Galaxies
Cassandra Lochhaas, Smita Mathur, Stephan Frank +6
High signal-to-noise spectra toward background quasars are crucial for uncovering weak absorption in the circumgalactic medium (CGM) of intervening galaxies, such as the diagnostic…
The hyperluminous Compton-thick quasar nucleus of the hot DOG W1835+4355 observed by NuSTAR
L. Zappacosta, E. Piconcelli, F. Duras +11
We present a 155ks NuSTAR observation of the hot dust-obscured galaxy (hot DOG) W1835+4355. We extracted spectra from the two NuSTAR detectors and analyzed them jointly wi…
The interacting late-type host galaxy of the radio-loud narrow-line Seyfert 1 IRAS 20181-2244
M. Berton, E. Congiu, S. Ciroi +15
Narrow-line Seyfert 1 galaxies (NLS1s) are a class of active galactic nuclei (AGN) which are known to be one of the few sources of rays, which originate in a relativistic beame…
