DOI: 10.1093/mnras/staa1872
Abstract: M31-2015-LRN is a likely stellar merger discovered in the Andromeda Galaxy in 2015. We present new optical to mid-infrared photometry and optical spectroscopy for this event. The transient brightened by ∼3 mag as compared to… read more here.

DOI: 10.1093/mnras/staa317
Abstract: We revisit the orbital history of the Triangulum galaxy (M33) around the Andromeda galaxy (M31) in view of the recent Gaia Data Release 2 proper motion measurements for both Local Group galaxies. Earlier studies consider… read more here.

DOI: 10.1093/mnras/stad1430
Abstract: We use young clusters and giant molecular clouds (GMCs) in the galaxies M33 and M31 to constrain temporal and spatial scales in the star formation process. In M33, we compare the PHATTER catalogue of 1214… read more here.

DOI: 10.1093/mnras/stae2024
Abstract: A superbubble is a hot, dilute, and X-ray-emitting gas cavity produced by stellar winds and supernova explosions. It is an intriguing feature for the study of stellar feedback processes. We report a study of possible… read more here.

DOI: 10.1093/mnras/stae2327
Abstract: We present results of our dynamical stream modelling for the North West Stream in the outer halo of the Andromeda galaxy (M31). Comprising two main segments, the North West Stream was thought to be a… read more here.

DOI: 10.1093/mnras/staf1978
Abstract: The arrangement of M31’s dwarf galaxies exhibits anisotropy, with the majority located in the hemisphere between the Milky Way and the host galaxy. This study aims to investigate whether M31’s present location is aligned with… read more here.

Tidal stripping as a mechanism for placing globular clusters on wide orbits: the case of MGC1 in M31
Sign Up to like & getrecommendations! Published in 2019 at "Monthly Notices of the Royal Astronomical Society"
DOI: 10.1093/mnras/stz709
Abstract: The globular clusters of large spiral galaxies can be divided into two populations: one that formed in situ and one that comprises clusters tidally stripped away from other galaxies. In this paper, we investigate the… read more here.
