Spatial Extent of Molecular Gas, Dust, and Stars in Massive Galaxies at z ∼ 2.2–2.5 Determined with ALMA and JWST

open access: yesThe Astrophysical Journal Letters, 2023
We present the results of 0.″6-resolution observations of CO J = 3 − 2 line emission in 10 massive star-forming galaxies at z ∼ 2.2–2.5 with the Atacama Large Millimeter/submillimeter Array (ALMA).

Galaxies at High Redshift [PDF]

open access: yes, 2000
Within just the last few years, we have advanced from knowing only a few galaxies at z>2 to having redshifts for nearly 1000 z~2-5 objects. The majority of this sample has been detected through the photometric ``drop-out'' technique used so successfully by Steidel and his collaborators. In addition, a handful of objects have already been detected at

The circumgalactic medium of high-redshift galaxies [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society: Letters, 2014
Abstract We study the properties of the circumgalactic medium (CGM) of high-z galaxies in the metal enrichment simulations presented in Pallottini et al. At z = 4, we find that the simulated CGM gas density profiles are self-similar, once scaled with the virial radius of the parent dark matter halo.

Modelling galaxy clustering at high redshift [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 1998
We discuss the theoretical interpretation of observational data concerning the clustering of galaxies at high redshifts. Building on the theoretical machinery developed by Matarrese et al. (1997), we make detailed quantitative predictions of galaxy clustering statistics for a variety of cosmological models, taking into account differences in spatial ...

In Pursuit of High Redshift Galaxies

open access: yes, 2016
Some contributions in Chap. 1 have highlighted the impact of the discovery in the 1960s of a handful of radio galaxies and Quasars in the redshift range z ∼ 0.2-0.4. About 40 years later, at the end of the twentieth Century, the systematic exploration of galaxies reached z ∼ 1-3.

The IRX–β relation of high-redshift galaxies [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2021
ABSTRACT The relation between infrared excess (IRX) and UV spectral slope (βUV) is an empirical probe of dust properties of galaxies. The shape, scatter, and redshift evolution of this relation are not well understood, however, leading to uncertainties in estimating the dust content and star formation rates (SFRs) of galaxies at high ...
