Inferring the intergalactic medium neutral fraction at z 6-8 with low-luminosity Lyman break galaxies
Pentericci, Laura; Treu, Tommaso; Bradač, Maruša +6 more
We present a Bayesian inference on the neutral hydrogen fraction of the intergalactic medium (IGM), $\overline{x}_{\small HI}$, at z ~ 6-8 using the properties of Lyman break galaxies (LBGs) during the epoch of reionization. We use large samples of LBG candidates at 5.5 ≤ z ≤ 8.2 with spectroscopy from Keck/DEIMOS and Keck/MOSFIRE. For each galaxy…
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…
Detection of Ongoing Mass Loss from HD 63433c, a Young Mini-Neptune
Henry, Gregory W.; Knutson, Heather A.; Dai, Fei +9 more
We detect Lyα absorption from the escaping atmosphere of HD 63433c, a R = 2.67R ⊕, P = 20.5 day mini-Neptune orbiting a young (440 Myr) solar analog in the Ursa Major Moving Group. Using Hubble Space Telescope (HST)/Space Telescope Imaging Spectrograph, we measure a transit depth of 11.1 ± 1.5% in the blue wing and 8 ± 3% in the red. Th…
Gigaelectronvolt emission from a compact binary merger
Campana, Sergio; Salafia, Om Sharan; Giarratana, Stefano +9 more
An energetic γ-ray burst (GRB), GRB 211211A, was observed on 11 December 20211,2. Despite its long duration, typically associated with bursts produced by the collapse of massive stars, the observation of an optical-infrared kilonova points to a compact binary merger origin3. Here we report observations of a significant (more …
ALMA Lensing Cluster Survey: Hubble Space Telescope and Spitzer Photometry of 33 Lensed Fields Built with CHArGE
Magdis, G. E.; Wang, T.; Bauer, F. E. +30 more
We present a set of multiwavelength mosaics and photometric catalogs in the Atacama Large Millimeter/submillimeter Array (ALMA) lensing cluster survey fields. The catalogs were built by the reprocessing of archival data from the Complete Hubble Archive for Galaxy Evolution compilation, taken by the Hubble Space Telescope (HST) in the Reionization …
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…
The Hubble Tension Revisited: Additional Local Distance Ladder Uncertainties
Dhawan, Suhail; Goobar, Ariel; Mörtsell, Edvard +1 more
In a recent paper, we investigated possible systematic uncertainties related to the Cepheid color-luminosity calibration method and their influence on the tension between the Hubble constant as inferred from distances to Type Ia supernovae and the cosmic microwave background as measured with the Planck satellite. Here, we study the impact of other…
A multimission catalogue of ultraluminous X-ray source candidates
Earnshaw, H. P.; Roberts, T. P.; Mateos, S. +4 more
We present a new, multimission catalogue of ultraluminous X-ray source (ULX) candidates, based on recent data releases from each of the XMM-Newton, Swift, and Chandra observatories (the 4XMM-DR10, 2SXPS, and CSC2 catalogues, respectively). This has been compiled by cross-correlating each of these X-ray archives with a large sample of galaxies prim…
The quenching of galaxies, bulges, and disks since cosmic noon. A machine learning approach for identifying causality in astronomical data
Maiolino, Roberto; Ellison, Sara L.; Conselice, Christopher J. +4 more
We present an analysis of the quenching of star formation in galaxies, bulges, and disks throughout the bulk of cosmic history, from z = 2 − 0. We utilise observations from the Sloan Digital Sky Survey and the Mapping Nearby Galaxies at Apache Point Observatory survey at low redshifts. We complement these data with observations from the Cosmic Ass…
