HELP: the Herschel Extragalactic Legacy Project
Aussel, H.; Shirley, R.; Buat, V. +29 more
We present the Herschel Extragalactic Legacy Project (HELP). This project collates, curates, homogenizes, and creates derived data products for most of the premium multiwavelength extragalactic data sets. The sky boundaries for the first data release cover 1270 deg2 defined by the Herschel SPIRE extragalactic survey fields; notably the …
The Large Early Galaxy Astrophysics Census (LEGA-C) Data Release 3: 3000 High-quality Spectra of Ks-selected Galaxies at z > 0.6
Bell, Eric F.; Maseda, Michael V.; D'Eugenio, Francesco +19 more
We present the third and final data release of the Large Early Galaxy Astrophysics Census (LEGA-C), an ESO/Very Large Telescope public spectroscopic survey targeting 0.6 < z < 1.0, Ks-selected galaxies. The data release contains 3528 spectra with measured stellar velocity dispersions and stellar population properties, a 25-fold in…
Disk Evolution Study Through Imaging of Nearby Young Stars (DESTINYS): Late Infall Causing Disk Misalignment and Dynamic Structures in SU Aur
Flock, Mario; Ménard, François; Bae, Jaehan +19 more
Gas-rich circumstellar disks are the cradles of planet formation. As such, their evolution will strongly influence the resulting planet population. In the ESO DESTINYS large program, we study these disks within the first 10 Myr of their development with near-infrared scattered-light imaging. Here we present VLT/SPHERE polarimetric observations of …
Probing cosmic dawn: Ages and star formation histories of candidate z ≥ 9 galaxies
Chisholm, J.; Laporte, N.; Ellis, R. S. +3 more
We discuss the spectral energy distributions and physical properties of six galaxies whose photometric redshifts suggest they lie beyond a redshift z ≃ 9. Each was selected on account of a prominent excess seen in the Spitzer/IRAC 4.5 $\mu$m band which, for a redshift above z = 9.0, likely indicates the presence of a rest-frame Balmer break and a …
The Global Meteor Network - Methodology and first results
Vida, Denis; Brown, Peter G.; Mazur, Michael J. +10 more
The Global Meteor Network (GMN) utilizes highly sensitive low-cost CMOS video cameras which run open-source meteor detection software on Raspberry Pi computers. Currently, over 450 GMN cameras in 30 countries are deployed. The main goal of the network is to provide long-term characterization of the radiants, flux, and size distribution of annual m…
SPICY: The Spitzer/IRAC Candidate YSO Catalog for the Inner Galactic Midplane
Hillenbrand, Lynne A.; Povich, Matthew S.; Kuhn, Michael A. +5 more
We present ∼120,000 Spitzer/IRAC candidate young stellar objects (YSOs) based on surveys of the Galactic midplane between ℓ ∼ 255° and 110°, including the GLIMPSE I, II, and 3D, Vela-Carina, Cygnus X, and SMOG surveys (613 square degrees), augmented by near-infrared catalogs. We employed a classification scheme that uses the flexibility of a tailo…
Slow-Mode Magnetoacoustic Waves in Coronal Loops
Reale, Fabio; Srivastava, Abhishek K.; Ofman, Leon +3 more
Rapidly decaying long-period oscillations often occur in hot coronal loops of active regions associated with small (or micro-) flares. This kind of wave activity was first discovered with the SOHO/SUMER spectrometer from Doppler velocity measurements of hot emission lines, thus also often called "SUMER" oscillations. They were mainly interpreted a…
A bright γ-ray flare interpreted as a giant magnetar flare in NGC 253
Mitrofanov, I.; Hurley, K.; von Kienlin, A. +33 more
Soft γ-ray repeaters exhibit bursting emission in hard X-rays and soft γ-rays. During the active phase, they emit random short (milliseconds to several seconds long), hard-X-ray bursts, with peak luminosities1 of 1036 to 1043 erg per second. Occasionally, a giant flare with an energy of around 1044 to 10…
SPECULOOS: Ultracool dwarf transit survey. Target list and strategy
Queloz, D.; Delrez, L.; Gillon, M. +20 more
Context. One of the most promising avenues for the detailed study of temperate Earth-sized exoplanets is the detection of such planets in transit in front of stars that are small and near enough to make it possible to carry out a thorough atmospheric characterisation with next-generation telescopes, such as the James Webb Space telescope (JWST) or…
Hubble tension or a transition of the Cepheid SnIa calibrator parameters?
Perivolaropoulos, Leandros; Skara, Foteini
We reanalyze the Cepheid data used to infer the value of the Hubble constant H0 by calibrating type Ia supernovae. We do not enforce a universal value of the empirical Cepheid calibration parameters RW (Cepheid Wesenheit color-luminosity parameter) and MHW (Cepheid Wesenheit H-band absolute magnitude). I…
