The XMM-Newton serendipitous survey. IX. The fourth XMM-Newton serendipitous source catalogue
DOI: 10.1051/0004-6361/201937353 Bibcode: 2020A&A...641A.136W

Motch, C.; Page, M. J.; Ballet, J. +28 more

Context. Sky surveys produce enormous quantities of data on extensive regions of the sky. The easiest way to access this information is through catalogues of standardised data products. XMM-Newton has been surveying the sky in the X-ray, ultra-violet, and optical bands for 20 years.
Aims: The XMM-Newton Survey Science Centre has been producin…

X-CIGALE: Fitting AGN/galaxy SEDs from X-ray to infrared
DOI: 10.1093/mnras/stz3001 Bibcode: 2020MNRAS.491..740Y

Ciesla, L.; Papovich, C.; Brandt, W. N. +6 more

Code Investigating GALaxy Emission (CIGALE) is a powerful multiwavelength spectral energy distribution (SED) fitting code for extragalactic studies. However, the current version of CIGALE is not able to fit X-ray data, which often provide unique insights into active galactic nucleus (AGN) intrinsic power. We develop a new X-ray module for CIGALE, …

Rotation of Low-mass Stars in Taurus with K2
DOI: 10.3847/1538-3881/ab893c Bibcode: 2020AJ....159..273R

Bouvier, J.; Rebull, L. M.; Stauffer, J. R. +4 more

We present an analysis of K2 light curves (LCs) from Campaigns 4 and 13 for members of the young (∼3 Myr) Taurus association, in addition to an older (∼30 Myr) population of stars that is largely in the foreground of the Taurus molecular clouds. Out of 156 of the highest-confidence Taurus members, we find that 81% are periodic. Our sample of young…

MIRACLES: atmospheric characterization of directly imaged planets and substellar companions at 4-5 µm. I. Photometric analysis of β Pic b, HIP 65426 b, PZ Tel B, and HD 206893 B
DOI: 10.1051/0004-6361/201937159 Bibcode: 2020A&A...635A.182S

Quanz, S. P.; Todorov, K. O.; Stolker, T. +6 more

Context. Directly imaged planets and substellar companions are key targets for the characterization of self-luminous atmospheres. Their photometric appearance at 4-5 µm is sensitive to the chemical composition and cloud content of their atmosphere.
Aims: We aim to systematically characterize the atmospheres of directly imaged low-mass c…

All the PAHs: An AKARI-Spitzer Cross-archival Spectroscopic Survey of Aromatic Emission in Galaxies
DOI: 10.3847/1538-4357/abc002 Bibcode: 2020ApJ...905...55L

Baba, Shunsuke; Imanishi, Masatoshi; Lai, Thomas S. -Y. +2 more

We present a large sample of 2.5-38 µm galaxy spectra drawn from a cross-archival comparison in the AKARI-Spitzer Extragalactic Spectral Survey, and investigate a subset of 113 star-forming galaxies with prominent polycyclic aromatic hydrocarbon (PAH) emission spanning a wide range of star formation properties. With AKARI's extended 2.5-5 &m…

Millimeter-wave Point Sources from the 2500 Square Degree SPT-SZ Survey: Catalog and Population Statistics
DOI: 10.3847/1538-4357/ab9df7 Bibcode: 2020ApJ...900...55E

Chapman, S.; Bleem, L. E.; Stalder, B. +45 more

We present a catalog of emissive point sources detected in the SPT-SZ survey, a contiguous 2530 square degree area surveyed with the South Pole Telescope (SPT) from 2008-2011 in three bands centered at 95, 150, and 220 GHz. The catalog contains 4845 sources measured at a significance of 4.5σ or greater in at least one band, corresponding to detect…

ISPY-NACO Imaging Survey for Planets around Young stars. Survey description and results from the first 2.5 years of observations
DOI: 10.1051/0004-6361/201937000 Bibcode: 2020A&A...635A.162L

Queloz, D.; Quanz, S. P.; Avenhaus, H. +21 more

Context. The occurrence rate of long-period (a ≳ 50 au) giant planets around young stars is highly uncertain since it is not only governed by the protoplanetary disc structure and planet formation process, but also reflects both dynamical re-structuring processes after planet formation as well as possible capture of planets not formed in situ. Dir…

Search for Optically Dark Infrared Galaxies without Counterparts of Subaru Hyper Suprime-Cam in the AKARI North Ecliptic Pole Wide Survey Field
DOI: 10.3847/1538-4357/ab9cb7 Bibcode: 2020ApJ...899...35T

Momose, Rieko; Hashimoto, Tetsuya; Goto, Tomotsugu +25 more

We present the physical properties of AKARI sources without optical counterparts in optical images from the Hyper Suprime-Cam (HSC) on the Subaru telescope. Using the AKARI infrared (IR) source catalog and HSC optical catalog, we select 583 objects that do not have HSC counterparts in the AKARI North Ecliptic Pole wide survey field (∼5 deg2

ALMA Survey of Orion Planck Galactic Cold Clumps (ALMASOP). II. Survey Overview: A First Look at 1.3 mm Continuum Maps and Molecular Outflows
DOI: 10.3847/1538-4365/abba26 Bibcode: 2020ApJS..251...20D

Sanhueza, Patricio; Ward-Thompson, Derek; Kwon, Woojin +32 more

Planck Galactic Cold Clumps (PGCCs) are considered to be the ideal targets to probe the early phases of star formation. We have conducted a survey of 72 young dense cores inside PGCCs in the Orion complex with the Atacama Large Millimeter/submillimeter Array (ALMA) at 1.3 mm (band 6) using three different configurations (resolutions ∼0"35, 1"0, an…

A basin-free spherical shape as an outcome of a giant impact on asteroid Hygiea
DOI: 10.1038/s41550-019-0915-8 Bibcode: 2020NatAs...4..136V

Jorda, L.; Lamy, P.; Colas, F. +44 more

(10) Hygiea is the fourth largest main belt asteroid and the only known asteroid whose surface composition appears similar to that of the dwarf planet (1) Ceres1,2, suggesting a similar origin for these two objects. Hygiea suffered a giant impact more than 2 Gyr ago3 that is at the origin of one of the largest asteroid famili…
