The Gas and Stellar Content of a Metal-poor Galaxy at z = 8.496 as Revealed by JWST and ALMA [PDF]

Astrophysical Journal Letters, 2022
We present a joint analysis of the galaxy S04590 at z = 8.496 based on NIRSpec, NIRCam, and NIRISS observations obtained as part of the Early Release Observations program of the James Webb Space Telescope (JWST) and the far-infrared [C ii] 158 μm ...

Simulating the Legacy Survey of Space and Time Stellar Content with TRILEGAL [PDF]

Astrophysical Journal Supplement Series, 2022
We describe a large simulation of the stars to be observed by the Vera C. Rubin Observatory Legacy Survey of Space and Time (LSST). The simulation is based on the TRILEGAL code, which resorts to large databases of stellar evolutionary tracks, synthetic ...

Missing Giants: Predictions on Dust-obscured Galaxy Stellar Mass Assembly Throughout Cosmic Time [PDF]

Astrophysical Journal, 2022
Due to their extremely dust-obscured nature, much uncertainty still exists surrounding the stellar mass growth and content in dusty, star-forming galaxies (DSFGs) at z > 1. In this work, we present a numerical model built using empirical data on DSFGs to

Confirmation of an Anomalously Low Dark Matter Content for the Galaxy NGC 1052-DF4 from Deep, High-resolution Continuum Spectroscopy [PDF]

Astrophysical Journal, 2023
NGC 1052-DF4 was found to be the second “galaxy lacking dark matter” in the NGC 1052 group, based on its velocity dispersion of σgc=4.2−2.2+4.4 km s−1 as measured from the radial velocities of seven of its globular clusters. Here we verify this result by

The Large Magellanic Cloud stellar content with SMASH [PDF]

Astronomy & Astrophysics, 2020
The Large Magellanic Cloud (LMC) is the closest and most studied example of an irregular galaxy. Among its principal defining morphological features, its off-centred bar and single spiral arm stand out, defining a whole family of galaxies known as the ...

Physical correlations of the scatter between galaxy mass, stellar content, and halo mass [PDF]

Monthly notices of the Royal Astronomical Society, 2019
We use the UniverseMachine to analyse the source of scatter between the central galaxy mass, the total stellar mass in the halo, and the dark matter halo mass, for massive (Mvir > 1013 M⊙) haloes.

A Malin 1 ‘cousin’ with counter-rotation: internal dynamics and stellar content of the giant low surface brightness galaxy UGC 1922 [PDF]

Monthly notices of the Royal Astronomical Society, 2018
The formation scenario for giant low surface brightness (gLSB) galaxies with discs as large as 100 kpc still remains unclear. These stellar systems are rare and very hard to observe, therefore a detailed insight on every additional object helps to ...

Mapping stellar content to dark matter haloes - III. Environmental dependence and conformity of galaxy colours [PDF]

, 2017
Recent studies suggest that the quenching properties of galaxies are correlated over several mega-parsecs. The large-scale "galactic conformity" phenomenon around central galaxies has been regarded as a potential signature of "galaxy assembly bias" or ...

Mapping stellar content to dark matter haloes using galaxy clustering and galaxy–galaxy lensing in the SDSS DR7 [PDF]

, 2015
The mapping between the distributions of the observed galaxy stellar mass and the underlying dark matter halos provides the crucial link from theories of large‐scale structure formation to interpreting the complex phenomena of galaxy formation and ...

Mapping stellar content to dark matter haloes – II. Halo mass is the main driver of galaxy quenching [PDF]

, 2015
We develop a simple yet comprehensive method to distinguish the underlying drivers of galaxy quenching, using the clustering and galaxy-galaxy lensing of red and blue galaxies in SDSS.
