JADES Initial Data Release for the Hubble Ultra Deep Field: Revealing the Faint Infrared Sky with Deep JWST NIRCam Imaging

open access: yesThe Astrophysical Journal Supplement Series, 2023
JWST has revolutionized the field of extragalactic astronomy with its sensitive and high-resolution infrared view of the distant Universe. Adding to the new legacy of JWST observations, we present the first NIRCam imaging data release from the JWST ...

Early Results From GLASS-JWST. XII. The Morphology of Galaxies at the Epoch of Reionization

open access: yesThe Astrophysical Journal Letters, 2023
Star-forming galaxies can exhibit strong morphological differences between the rest-frame far-UV and optical, reflecting inhomogeneities in star formation and dust attenuation.

The differential magnification of high-redshift ultraluminous infrared galaxies [PDF]

open access: yes, 1998
A class of extremely luminous high-redshift galaxies has recently been detected in unbiased submillimetre-wave surveys using the Submillimetre Common-User Bolometer Array (SCUBA) camera at the James Clerk Maxwell Telescope.

Disk Galaxies at High Redshift? [PDF]

open access: yesProceedings of the International Astronomical Union, 2007
AbstractThe successful implementation of integral field near-infrared spectrographs fed by adaptive optics is providing unprecedented views of gas motions within galaxies at redshifts z = 2 − 3, when the universe was forming stars at its peak rate. A complex picture of galaxy kinematics is emerging, with inflows, rotation within sometimes extended and ...

Searching for high-z DSFGs with NIKA2 and NOEMA [PDF]

open access: yesEPJ Web of Conferences, 2022
As the possible progenitors of passive galaxies at z=2-3, dusty starforming galaxies (DSFGs) at z>4 provide a unique perspective to study the formation, assembly, and early quenching of massive galaxies in the early Universe.

Structural and Morphological Properties of Ultraluminous Infrared Galaxies at 1 < z < 3

open access: yesOpen Astronomy, 2015
Using the Hubble Space Telescope (HST)/Wide Field Camera 3 (WFC3) near-infrared high-resolution imaging from the 3D-HST survey, we analyze the morphology and structure of 502 ultraluminous infrared galaxies (ULIRGs; LIR > 1012L⊙) at 1 < z < 3. Their rest-

The build-up of the colour-magnitude relation in galaxy clusters since z~0.8 [PDF]

open access: yes, 2006
Using galaxy clusters from the ESO Distant Cluster Survey, we study how the distribution of galaxies along the colour-magnitude relation has evolved since z~0.8.

Early Results from GLASS-JWST. XV. Properties of the Faintest Red Sources in the NIRCAM Deep Fields

open access: yesThe Astrophysical Journal Letters, 2023
We present a first look at the reddest 2–5 μ m sources found in deep images from the GLASS Early Release Science program. We undertake a general search, i.e., not looking for any particular spectral signatures, for sources detected only in

The K20 survey. IV. The redshift distribution of Ks<20 galaxies: a test of galaxy formation models [PDF]

open access: yes, 2002
We present the redshift distribution of a complete sample of 480 galaxies with Ks1 and z>1.5 respectively. A ``blind'' comparison is made with the predictions of a set of the most recent LambdaCDM hierarchical merging and pure luminosity evolution (PLE ...

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 ...
