The eROSITA Final Equatorial Depth Survey (eFEDS). X-ray catalogue
Finoguenov, A.; Haberl, F.; Schrabback, T. +35 more
Context. The eROSITA X-ray telescope on board the Spectrum-Poentgen-Gamma (SPG) observatory combines a large field of view and a large collecting area in the energy range between ~0.2 and ~8.0 keV. This gives the telescope the capability to perform uniform scanning observations of large sky areas.
Aims: SRG/eROSITA performed scanning observat…
Early Results from GLASS-JWST. III. Galaxy Candidates at z 9-15
Santini, Paola; Calabrò, Antonello; Castellano, Marco +27 more
We present the results of a first search for galaxy candidates at z ~ 9-15 on deep seven-band NIRCam imaging acquired as part of the GLASS-James Webb Space Telescope (JWST) Early Release Science Program on a flanking field of the Frontier Fields cluster A2744. Candidates are selected via two different renditions of the Lyman-break technique, isola…
A kilonova following a long-duration gamma-ray burst at 350 Mpc
Kilpatrick, Charles D.; Izzo, Luca; Smith, Nathan +32 more
Gamma-ray bursts (GRBs) are divided into two populations1,2; long GRBs that derive from the core collapse of massive stars (for example, ref. 3) and short GRBs that form in the merger of two compact objects4,5. Although it is common to divide the two populations at a gamma-ray duration of 2 s, classification based …
Third data release of the Hyper Suprime-Cam Subaru Strategic Program
Ono, Yoshiaki; Ouchi, Masami; Harikane, Yuichi +64 more
This paper presents the third data release of the Hyper Suprime-Cam Subaru Strategic Program (HSC-SSP), a wide-field multi-band imaging survey with the Subaru 8.2 m telescope. HSC-SSP has three survey layers (Wide, Deep, and UltraDeep) with different area coverages and depths, designed to address a wide array of astrophysical questions. This third…
A repeating fast radio burst source in a globular cluster
Lindqvist, M.; Lazio, T. J. W.; Ransom, S. M. +63 more
Fast radio bursts (FRBs) are flashes of unknown physical origin1. The majority of FRBs have been seen only once, although some are known to generate multiple flashes2,3. Many models invoke magnetically powered neutron stars (magnetars) as the source of the emission4,5. Recently, the discovery6 of another…
Fast radio bursts at the dawn of the 2020s
Lorimer, D. R.; Hessels, J. W. T.; Petroff, E.
Since the discovery of the first fast radio burst (FRB) in 2007, and their confirmation as an abundant extragalactic population in 2013, the study of these sources has expanded at an incredible rate. In our 2019 review on the subject, we presented a growing, but still mysterious, population of FRBs—60 unique sources, 2 repeating FRBs, and only 1 i…
2021 Census of Interstellar, Circumstellar, Extragalactic, Protoplanetary Disk, and Exoplanetary Molecules
McGuire, Brett A.
To date, 241 individual molecular species, composed of 19 different elements, have been detected in the interstellar and circumstellar medium by astronomical observations. These molecules range in size from two atoms to 70 and have been detected across the electromagnetic spectrum from centimeter wavelengths to the ultraviolet. This census present…
Unveiling the Universe with emerging cosmological probes
Izzo, Luca; Verde, Licia; Risaliti, Guido +22 more
The detection of the accelerated expansion of the Universe has been one of the major breakthroughs in modern cosmology. Several cosmological probes (Cosmic Microwave Background, Supernovae Type Ia, Baryon Acoustic Oscillations) have been studied in depth to better understand the nature of the mechanism driving this acceleration, and they are being…
Ram pressure stripping in high-density environments
Fossati, Matteo; Sun, Ming; Boselli, Alessandro
Galaxies living in rich environments are suffering different perturbations able to drastically affect their evolution. Among these, ram pressure stripping, i.e. the pressure exerted by the hot and dense intracluster medium (ICM) on galaxies moving at high velocity within the cluster gravitational potential well, is a key process able to remove the…
The JWST Early Release Observations
Koekemoer, Anton M.; Ravindranath, Swara; Henry, Alaina +34 more
The James Webb Space Telescope (JWST) Early Release Observations (EROs) is a set of public outreach products created to mark the end of commissioning and the beginning of science operations for JWST. Colloquially known as the "Webb First Images and Spectra," these products were intended to demonstrate to the worldwide public that JWST is ready for…
