Supermassive black holes (SMBHs) are a key catalyst of galaxy formation and evolution,
leading to an observed correlation between SMBH mass M BH and host galaxy velocity …

We use data from the JWST Public Release IMaging for Extragalactic Research survey to
measure the size scaling relations of 1668 rest-frame UV-bright Lyman-break galaxies …

We present astrophot, a fast, powerful, and user-friendly python based astronomical image
photometry solver. astrophot incorporates automatic differentiation and graphics processing …

Quasars experiencing strong lensing offer unique viewpoints on subjects related to the
cosmic expansion rate, the dark matter profile within the foreground deflectors, and the …

In a strong gravitational lensing system, the distorted light from a source is analysed to infer
the properties of the lens. However, light emitted by the lens itself can contaminate the …

The cold dark matter (DM) model predicts that every galaxy contains thousands of DM
subhaloes; almost all other DM models include a physical process that smooths away the …

Observations suggest that the dark matter and stars in early-type galaxies 'conspire'to
produce a surprisingly simple distribution of total mass, ρ (r)∝ ρ− γ, with γ≈ 2. We measure …

While quiescent galaxies have comparable amounts of cool gas in their outer circumgalactic
medium (CGM) compared to star-forming galaxies, they have significantly less interstellar …

Massive star-forming galaxies in the high-redshift universe host large reservoirs of cold gas
in their circumgalactic medium (CGM). Traditionally, these reservoirs have been linked to …

We examine the morphological and kinematical properties of SPT-2147, a strongly lensed,
massive, dusty, star-forming galaxy at $ z= 3.762$. Combining data from JWST, HST, and …
