Multicomponent kinematics in a massive filamentary IRDC
Vlas Sokolov, Ke Wang, Jaime E. Pineda +6
To probe the initial conditions for high-mass star and cluster formation, we investigate the properties of dense filaments within the infrared dark cloud G035.39-00.33 (IRDC G035.3…
Does the mid-infrared-hard X-ray luminosity relation for active galactic nuclei depend on Eddington ratio?
Yoshiki Toba, Yoshihiro Ueda, Kenta Matsuoka +5
We revisit the correlation between the mid-infrared (6 m) and hard X-ray (2--10 keV) luminosities of active galactic nuclei (AGNs) to understand the physics behind it. We constr…
IRAM and Gaia views of multi-episodic star formation in IC1396A: The origin and dynamics of the Class 0 protostar at the edge of an HII region
Aurora Sicilia-Aguilar, Nimesh Patel, Min Fang +3
(Abridged) IC1396A is a cometary globule containing the Class 0 source IC1396A-PACS-1. We use IRAM 30m and Gaia DR2 data to explore the star-formation history of IC1396A and invest…
The main sequence of star forming galaxies I. The local relation and its bending
P. Popesso, A. Concas, L. Morselli +11
By using a set of different SFR indicators, including WISE mid-infrared and Halpha emission, we study the slope of the Main Sequence (MS) of local star forming galaxies at stellar…
New Near-Infrared light-curve templates for RR Lyrae variables
V. F. Braga, P. B. Stetson, G. Bono +34
We provide homogeneous optical (UBVRI) and near-infrared (JHK) time series photometry for 254 cluster (omega Cen, M4) and field RR Lyrae (RRL) variables. We ended up with more than…
The Dissolution of Clusters: What Can We Learn from Nearby, UV-bright, Overluminous Field Stars?
Joel Kastner, Matthieu Chalifour, Alex Binks +3
The past two decades have seen dramatic progress in our knowledge of the population of young stars of age <200 Myr that lie within 150 pc of the Sun. These nearby, young stars, mos…
