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.

Saving Bambi from the mower? Using a drone with thermal camera to evaluate a low‐tech scaring technique to reduce roe deer fawn mortality during grass harvest

Wildlife Biology, Volume 2026, Issue 5, September 2026.
Roe deer is a species that hides their neonates as an anti‐predator strategy. This may prove efficient against mammalian predators, such as the red fox; however, it might be an ecological trap as large numbers of fawns are killed by tractors with harvesters each year during grass harvest.

The effect of the environment on the evolution of galaxy colours [PDF]

, 2006
In chapter 1 of this thesis, I give a brief overview of the birth of modern cosmology and the growth of the current paradigm. I then go on to describe the different types of galaxies, the star formation rates within them and give some notes about galaxy ...

A Mid‐Infrared Galaxy Atlas (MIGA) [PDF]

The Astrophysical Journal Supplement Series, 2000
A mid-infrared atlas of part of the Galactic plane ($75^\circ < l < 148^\circ, b = \pm6^\circ$) has been constructed using HIRES processed infrared data to provide a mid-infrared data set for the Canadian Galactic Plane Survey (CGPS). The addition of this data set to the CGPS will enable the study of the emission from the smallest components of ...

Determining Total Infrared Luminosities from Submillimeter Measurements of High-redshift Galaxies

The Astrophysical Journal
Determining total infrared luminosities for very high-redshift galaxies is important to estimate the rate of star formation in heavily dust-embedded environments.

Investigating Galactic Cosmic Ray Ionization’s Contribution to Aerosol Formation on Neptune and a Potential Link to the Relationship Between Brightness and Solar Activity

Journal of Geophysical Research: Planets, Volume 131, Issue 9, September 2026.
Abstract In this work we investigate how ionization from Galactic Cosmic Rays (GCRs) can affect aerosol nucleation on Neptune and discuss potential implications for the observed brightness variations that appear to follow the solar cycle. We calculate the planetary vertical cutoff rigidity for Neptune based on the O8 ${\mathrm{O}}_{8}$ magnetic field ...

Galaxy Zoo:dust in spiral galaxies [PDF]

, 2010
We investigate the effect of dust on spiral galaxies by measuring the inclination dependence of optical colours for 24 276 well-resolved Sloan Digital Sky Survey (SDSS) galaxies visually classified via the Galaxy Zoo project.

Prediction of Star Formation Rates Using an Artificial Neural Network

The Astrophysical Journal
In this study we develop an artificial neural network to estimate the infrared (IR) luminosity and star formation rates (SFR) of galaxies. Our network is trained using “true” IR luminosity values derived from modeling the IR spectral energy distributions

Estimating Molecular Gas Content in Galaxies from Polycyclic Aromatic Hydrocarbon Emission

The Astrophysical Journal, 2023
Emission from polycyclic aromatic hydrocarbons (PAHs), a commonly used indicator of star formation activity in galaxies, also has the potential to serve as an effective empirical tracer of molecular gas.
