The Hubble Arp Galaxy Survey

The Astrophysical Journal Supplement Series
The typical galaxy in the local Universe is expected to be in a self-regulated quasi-equilibrium, displaying a settled morphology that falls within the Hubble sequence.

Atacama Large Aperture Submillimeter Telescope (AtLAST) science: Gas and dust in nearby galaxies [version 2; peer review: 2 approved, 1 approved with reservations]

Open Research Europe
Understanding the physical processes that regulate star formation and galaxy evolution are major areas of activity in modern astrophysics. Nearby galaxies offer unique opportunities to inspect interstellar medium (ISM), star formation (SF), radiative ...

Galaxy clusters as astrophysical laboratories and probes of cosmology [PDF]

, 2014
Galaxy clusters are the most recent of cosmological structures to have formed by the present time in the currently favoured hierarchical scenario of structure formation and are widely regarded as powerful probes of cosmology and galaxy formation physics alike.

A catalog to unite them all: REGALADE, a revised galaxy compilation for the advanced detector era

Astronomy & Astrophysics
Context. Many applications in transient science, gravitational wave follow-up, and galaxy population studies require all-sky galaxy catalogs with reliable distances, extents, and stellar masses.

Color dichotomy and gradients in the bulges and disks of EFIGI galaxies along the Hubble sequence

Astronomy & Astrophysics
Context. One of the most outstanding questions in contemporary astrophysics is: What is the significance of galaxy morphology? What physical processes underlie the morphologies we observe and is a galaxy’s internal structure shaping its evolution (nature)

The Tip of Red Giant Branch Distances to Nearby Dwarf Galaxies WLM and Sextans A with JWST

The Astrophysical Journal
Distance measurements to extragalactic systems that are both accurate and precise are cornerstones of modern astrophysics, underpinning the calibration of standard candles and the determination of the Hubble constant.

ALMA and JWST Imaging of z > 6 Quasars: No Spatial Position Offset Observed between Quasars and Their Host Galaxies

The Astrophysical Journal
We present a study determining the spatial offset between the position of the supermassive black hole (as traced through their broad line regions) and the host galaxy in six z > 6 quasars.

First Light and Reionization Epoch Simulations (FLARES) -- XV: The physical properties of super-massive black holes and their impact on galaxies in the early universe

The Open Journal of Astrophysics
Understanding the co-evolution of super-massive black holes (SMBHs) and their host galaxies remains a key challenge of extragalactic astrophysics, particularly the earliest stages at high-redshift.
