JCMT Mapping of CO(3-2) in the Circumnuclear Region of M31
Zongnan Li, Zhiyuan Li, Ping Zhou +3
We present a survey of CO(3-2) molecular line emission in the circumnuclear region of M31 with the James Clerk Maxwell Telescope (JCMT), aiming to explore the physical conditions o…
Two kinematically distinct old globular cluster populations in the Large Magellanic Cloud
Andrés E. Piatti, Emilio J. Alfaro, Tristan Cantat-Gaudin
We report results of proper motions of 15 known Large Magellanic Cloud (LMC) old globular clusters (GCs) derived from the Gaia DR2 data sets. When these mean proper motions are gat…
ROSETTA/OSIRIS observations of the 67P nucleus during the April 2016 flyby: high-resolution spectrophotometry
C. Feller, S. Fornasier, S. Ferrari +35
In April 2016, the Rosetta spacecraft performed a low-altitude low-phase-angle flyby over the Imhotep-Khepry transition of 67P/Churyumov-Gerasimenko's nucleus. The OSIRIS/Narrow-An…
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…
The link between brightest cluster galaxy properties and large scale extensions of 38 DAFT/FADA and CLASH clusters in the redshift range 0.2<z<0.9
F. Durret, Y. Tarricq, I. Márquez +2
In the context of large scale structure formation, clusters of galaxies are located at the nodes of the cosmic web, and continue to accrete galaxies and groups along filaments. The…
Revisiting the hardening of the stellar ionizing radiation in galaxy disks
E. Pérez-Montero, R. García-Benito, J. M. Vílchez
In this work we explore accurate new ways to derive the ionization parameter () and the equivalent effective temperature () in HII regions using emission-line intensities f…
