CONCERTO: Simulating the CO, [CII], and [CI] line emission of galaxies in a 117 field and the impact of field-to-field variance
A. Gkogkou, M. Béthermin, G. Lagache +29
In the submm regime, spectral line scans and line intensity mapping (LIM) are new promising probes for the cold gas content and star formation rate of galaxies across cosmic time.…
(Nearly) Model-Independent Constraints on the Neutral Hydrogen Fraction in the Intergalactic Medium at Using Dark Pixel Fractions in Ly and Ly Forests
Xiangyu Jin, Jinyi Yang, Xiaohui Fan +10
Cosmic reionization was the last major phase transition of hydrogen from neutral to highly ionized in the intergalactic medium (IGM). Current observations show that the IGM is sign…
Long Dark Gaps in the Ly Forest at : Evidence of Ultra Late Reionization from XQR-30 Spectra

Quantitative Constraints on the Reionization History from the IGM Damping Wing Signature in Two Quasars at z > 7
Frederick B. Davies, Joseph F. Hennawi, Eduardo Bañados +10
During reionization, neutral hydrogen in the intergalactic medium (IGM) imprints a damping wing absorption feature on the spectrum of high-redshift quasars. A detection of this sig…

We study the sub-mm properties of color-selected galaxies via a stacking analysis applied for the first time to interferometric data at sub-mm wavelengths. We base our study on 344…
Black hole mass estimates and emission-line properties of a sample of redshift z>6.5 quasars
G. De Rosa, B. P. Venemans, R. Decarli +10
We present the analysis of optical and near-infrared spectra of the only four quasars known to date, discovered in the UKIDSS-LAS and VISTA-VIKING surveys. Our data-set con…
The GISMO 2-millimeter Deep Field in GOODS-N
Johannes G. Staguhn, Attila Kovacs, Richard G. Arendt +15
We present deep continuum observations using the GISMO camera at a wavelength of 2 mm centered on the Hubble Deep Field (HDF) in the GOODS-N field. These are the first deep field o…
Dust May Be More Rare Than Expected in Metal Poor Galaxies
David B. Fisher, Alberto D. Bolatto, Rodrigo Herrera-Camus +7
'Normal' galaxies observed at z>6, when the Universe was <1 billion years old, thus far show no evidence of the cold dust that accompanies star formation in the local Universe, whe…

Investigating the presence of 500 um submillimeter excess emission in local star forming galaxies
Allison Kirkpatrick, Daniela Calzetti, Maud Galametz +10
Submillimeter excess emission has been reported at 500 microns in a handful of local galaxies, and previous studies suggest that it could be correlated with metal abundance. We inv…
The Starburst-Driven Molecular Wind in NGC 253 and the Suppression of Star Formation
Alberto D. Bolatto, Steven R. Warren, Adam K. Leroy +9
The under-abundance of very massive galaxies in the universe is frequently attributed to the effect of galactic winds. Although ionized galactic winds are readily observable most o…
