Secondary eclipses of WASP-18b -- Near Infrared observations with the Anglo Australian Telescope, the Magellan Clay Telescope and the LCOGT network
L. Kedziora-Chudczer, G. Zhou, J. Bailey +6
We present new eclipse observations for one of the hottest "hot Jupiters" WASP-18b, for which previously published data from HST WFC3 and Spitzer have led to radically conflicting…
HST/WFC3 grism observations of clusters: The cluster vs. field stellar mass-size relation and evidence for size growth of quiescent galaxies from minor mergers
Jasleen Matharu, Adam Muzzin, Gabriel B. Brammer +13
Minor mergers are thought to be responsible for the size growth of quiescent field galaxies with decreasing redshift. We test this hypothesis using the cluster environment as a lab…
Compton-thick AGN in the NuSTAR era III: A systematic study of the torus covering factor
Stefano Marchesi, Marco Ajello, Xiurui Zhao +9
We present the analysis of a sample of 35 candidate Compton thick (CT-) active galactic nuclei (AGNs) selected in the nearby Universe (average redshift <z>~0.03) with the Swift-BAT…
ALMA Observations of the Spatial Distribution of three CHO Isomers towards Sgr B2(N)
Ci Xue, Anthony J. Remijan, Andrew M. Burkhardt +1
The CHO isomers have been previously investigated primarily via disparate sets of observations involving single dish and array measurements. The only attempt at using a…
Clarifying the population of HMXBs in the Small Magellanic Cloud
Grigoris Maravelias, Andreas Zezas, Vallia Antoniou +2
Almost all confirmed optical counterparts of HMXBs in the SMC are OB stars with equatorial decretion disks (OBe). These sources emit strongly in Balmer lines and standout when imag…
LSST Cadence Optimization White Paper: The Definitive Map of the Galactic bulge
Oscar A. Gonzalez, Will Clarkson, Victor P. Debattista +14
We recommend configuring the LSST coverage of the inner Galactic plane to allow the production of the definitive age/metallicity map of the Galactic bulge from LSST data, matched t…
Disappearance of the extended main sequence turn-off in intermediate age clusters as a consequence of magnetic braking
C. Georgy, C. Charbonnel, L. Amard +8
Extended MS turn-offs are features commonly found in the colour-magnitude diagrams of young and intermediate age (less than about 2 Gyr) massive star clusters, where the MS turn-of…
K2 Ultracool Dwarfs Survey. V. High superflare rates on rapidly rotating late-M dwarfs
Rishi R. Paudel, John E. Gizis, D. J. Mullan +4
We observed strong superflares (defined as flares with energy in excess of 10^33 erg) on three late-M dwarfs: 2MASS J08315742+2042213 (hereafter 2M0831+2042; M7 V), 2MASS J08371832…
Polygram Stars: Resonant Tidal Excitation of Fundamental Oscillation Modes in Asynchronous Stellar Coalescence
Morgan MacLeod, Michelle Vick, Dong Lai +1
The prevalence of binary stars at close separations implies that many of these systems will interact or merge during the binary's lifetime. This paper presents hydrodynamic simulat…
Observations of the solar chromosphere with ALMA and comparison with theoretical models
R. Brajša, D. Sudar, I. Skokic +9
In this work we use solar observations with the ALMA radio telescope at the wavelength of 1.21 mm. The aim of the analysis is to improve understanding of the solar chromosphere, a…
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…
ACCESS: Ground-based Optical Transmission Spectroscopy of the Hot Jupiter WASP-4b
Alex Bixel, Benjamin V. Rackham, Dániel Apai +6
We present an optical transmission spectrum of the atmosphere of WASP-4b obtained through observations of four transits with Magellan/IMACS. Using a Bayesian approach to atmospheri…
The Sunyaev-Zel'dovich effect of simulated jet-inflated bubbles in clusters
Kristian Ehlert, Christoph Pfrommer, Rainer Weinberger +2
Feedback by active galactic nuclei (AGNs) is essential for regulating the fast radiative cooling of low-entropy gas at the centers of galaxy clusters and for reducing star formatio…
SOFIA Far Infrared Imaging Polarimetry of M82 and NGC 253: Exploring the Super-Galactic Wind
Terry Jay Jones, C. Darren Dowell, Enrique Lopez Rodriguez +22
We present Far-Infrared polarimetry observations of M82 at 53 and and NGC 253 at , which were taken with HAWC+ in polarimetry mode on the Stratospheric Ob…
