The Fate of the Milky Way–Andromeda System: To Merge or Not?

open access: yesThe Astrophysical Journal Letters
It has long been predicted that the Milky Way (MW) will eventually merge with Andromeda (M31), a view reinforced by Hubble Space Telescope measurements indicating a small M31 transverse velocity. However, using updated Gaia-based proper motions (PMs) and

The JWST Discovery of the Triply Imaged Type Ia “Supernova H0pe” and Observations of the Galaxy Cluster PLCK G165.7+67.0

open access: yesThe Astrophysical Journal
A Type Ia supernova (SN) at z = 1.78 was discovered in James Webb Space Telescope Near Infrared Camera imaging of the galaxy cluster PLCK G165.7+67.0 (G165; z = 0.35).

CSST Large-scale Structure Analysis Pipeline. IV. Cosmic Voids Identified from Galaxy Group Samples as Probes of the Large-scale Structure

open access: yesThe Astrophysical Journal
Because groups are directly associated with halos, they allow for considerably simpler theoretical modeling than approaches based on individual galaxies.

The M31–M33 Interaction: Impact on M31’s Center-of-mass Motion and Satellite Orbits

open access: yesThe Astrophysical Journal
Inspired by recent studies of the interaction between the Milky Way and the Large Magellanic Cloud and its implications for the Milky Way’s global dynamical history, we investigate how the massive satellite galaxy M33 influences the position and velocity

The PAndAS View of the Andromeda Satellite System. IV. Global Properties

open access: yesThe Astrophysical Journal, 2023
We build a statistical framework to infer the global properties of the satellite system of the Andromeda galaxy (M31) from the properties of individual dwarf galaxies located in the Pan-Andromeda Archaelogical Survey (PAndAS) and the previously ...

Simulating supernova feedback in galaxy disks [PDF]

open access: yes, 2012
In this thesis I examine supernova feedback in hydrodynamical simulations of galaxy disks. Understanding this process entails the numerical evaluation of cooling in radiative shocks, and we present a set of simulations using two widely used numerical ...

Galaxy and mass assembly (GAMA) : end of survey report and data release 2 [PDF]

open access: yes, 2015
The Galaxy And Mass Assembly (GAMA) survey is one of the largest contemporary spectroscopic surveys of low redshift galaxies. Covering an area of ~286 deg2 (split among five survey regions) down to a limiting magnitude of r
