The interstellar medium in the Seyfert galaxy NGC 7172

, 1994
We present aperture and surface photometry of the Seyfert galaxy NGC 7172, which is a member of the compact group HCG90, and has a prominent equatorial dust lane. We use the observed colour excess in the dust lane, obtained from broad-band B and V images,

The clustering of galaxies in hierarchical galaxy formation models [PDF]

, 2010
Galaxy clustering encodes information about the values of cosmological parameters and also about the physical processes behind galaxy formation and evolution. The GALFORM semi-analytical model is the theoretical approach we used to model galaxy formation.

Generating astronomical spectra from photometry with conditional diffusion models [PDF]

, 2022
A trade-off between speed and information controls our understanding of astronomical objects. Fast-to-acquire photometric observations provide global properties, while costly and time-consuming spectroscopic measurements enable a better understanding of ...

A Holistic Exploration of the Potentially Recoverable Redshift Information of Stage IV Galaxy Surveys

The Astrophysical Journal
Extragalactic science and cosmology with Stage IV galaxy surveys will rely almost exclusively on redshift measurements derived solely from photometry, which are subject to systematic and statistical uncertainties with numerous analysis choices.

The Universe SPHEREx Will See: Empirically Based Galaxy Simulations and Redshift Predictions

The Astrophysical Journal
We simulate galaxy properties and redshift estimation for SPHEREx, the next NASA Medium Class Explorer. To make robust models of the galaxy population and test the spectrophotometric redshift performance for SPHEREx, we develop a set of synthetic ...
