A Long Time Ago in a Galaxy Far, Far Away: A Candidate z ∼ 12 Galaxy in Early JWST CEERS Imaging
Papovich, Casey; Cole, Justin W.; Yang, Guang +119 more
We report the discovery of a candidate galaxy with a photo-z of z ~ 12 in the first epoch of the James Webb Space Telescope (JWST) Cosmic Evolution Early Release Science Survey. Following conservative selection criteria, we identify a source with a robust z phot = ${11.8}_{-0.2}^{+0.3}$ (1σ uncertainty) with m F200W = 27.3 an…
A Search for H-Dropout Lyman Break Galaxies at z 12-16
Koekemoer, Anton M.; Yung, L. Y. Aaron; Harikane, Yuichi +11 more
We present two bright galaxy candidates at z ~ 12-13 identified in our H-dropout Lyman break selection with 2.3 deg2 near-infrared deep imaging data. These galaxy candidates, selected after careful screening of foreground interlopers, have spectral energy distributions showing a sharp discontinuity around 1.7 µm, a flat continuum …
A dusty compact object bridging galaxies and quasars at cosmic dawn
Marques-Chaves, R.; Magdis, G. E.; Colina, L. +18 more
Understanding how super-massive black holes form and grow in the early Universe has become a major challenge1,2 since it was discovered that luminous quasars existed only 700 million years after the Big Bang3,4. Simulations indicate an evolutionary sequence of dust-reddened quasars emerging from heavily dust-obscured starburs…
The Star Formation Rate of the Milky Way as Seen by Herschel
Martin, P. G.; Paladini, R.; Klessen, R. S. +23 more
We present a new derivation of the Milky Way's current star formation rate (SFR) based on the data of the Herschel InfraRed Galactic Plane Survey (Hi-GAL). We estimate the distribution of the SFR across the Galactic plane from the star-forming clumps identified in the Hi-GAL survey and calculate the total SFR from the sum of their contributions. T…
Dust, CO, and [C I]: cross-calibration of molecular gas mass tracers in metal-rich galaxies across cosmic time
Ivison, R. J.; Dunne, L.; Gomez, H. L. +2 more
We present a self-consistent cross-calibration of the three main molecular gas mass tracers in galaxies, namely the 12CO(1-0), [C I](3P1-3P0) lines, and the submm dust continuum emission, using a sample of 407 galaxies, ranging from local discs to submillimetre-selected galaxies (SMGs) up to z…
CMB/kSZ and Compton-y Maps from 2500 deg2 of SPT-SZ and Planck Survey Data
Bleem, L. E.; Stark, A. A.; George, E. M. +37 more
We present component-separated maps of the primary cosmic microwave background/kinematic Sunyaev-Zel'dovich (SZ) amplitude and the thermal SZ Compton-y parameter, created using data from the South Pole Telescope (SPT) and the Planck satellite. These maps, which cover the ~2500 deg2 of the southern sky imaged by the SPT-SZ survey, repres…
ALMA 200 pc Imaging of a z 7 Quasar Reveals a Compact, Disk-like Host Galaxy
Carilli, Chris; Fan, Xiaohui; Neeleman, Marcel +10 more
We present 0.″035 resolution (~200 pc) imaging of the 158 µm [C II] line and the underlying dust continuum of the z = 6.9 quasar J234833.34-305410.0. The 18 hour Atacama Large Millimeter/submillimeter Array observations reveal extremely compact emission (diameter ~1 kpc) that is consistent with a simple, almost face-on, rotation-supported di…
Accretion mode versus radio morphology in the LOFAR Deep Fields
Bondi, M.; Prandoni, I.; Shimwell, T. W. +17 more
Radio-loud active galaxies have two accretion modes [radiatively inefficient (RI) and radiatively efficient (RE)], with distinct optical and infrared signatures, and two jet dynamical behaviours, which in arcsec- to arcmin-resolution radio surveys manifest primarily as centre- or edge-brightened structures [Fanaroff-Riley (FR) class I and II]. The…
A3COSMOS: A census on the molecular gas mass and extent of main-sequence galaxies across cosmic time
Schinnerer, Eva; Liu, Daizhong; Kokorev, Vasily +6 more
Aims: We aim to constrain for the first time the mean mass and extent of the molecular gas of a mass-complete sample of normal > 1010 M⊙ star-forming galaxies at 0.4 < z < 3.6.
Methods: We apply an innovative uv-based stacking analysis to a large set of archival Atacama Large Millimeter/submillimeter Array …
Cosmic evolution of low-excitation radio galaxies in the LOFAR two-metre sky survey deep fields
Calistro Rivera, Gabriela; Małek, Katarzyna; Wang, Lingyu +16 more
Feedback from low-excitation radio galaxies (LERGs) plays a key role in the lifecycle of massive galaxies in the local Universe; their evolution, and the impact of these active galactic nuclei on early galaxy evolution, however, remain poorly understood. We use a sample of 10 481 LERGs from the first data release of the LOFAR two-metre Sky Survey …
