Merian: A Wide-Field Imaging Survey of Dwarf Galaxies at z~0.06-0.10

Shany Danieli, Erin Kado-Fong, Song Huang +32

We present the Merian Survey, an optical imaging survey optimized for studying the physical properties of bright star-forming dwarf galaxies. Merian is carried out with two medium-…

EDGE-INFERNO: Simulating every observable star in faint dwarf galaxies and their consequences for resolved-star photometric surveys

Eric P. Andersson, Martin P. Rey, Andrew Pontzen +4

Interpretation of data from faint dwarf galaxies is made challenging by observations limited to only the brightest stars. We present a major improvement to tackle this challenge by…

EDGE: Predictable Scatter in the Stellar Mass--Halo Mass Relation of Dwarf Galaxies

Stacy Y. Kim, Justin I. Read, Martin P. Rey +6

The stellar-mass--halo-mass (SMHM) relation is central to our understanding of galaxy formation and the nature of dark matter. However, its normalisation, slope, and scatter are hi…

Core formation by binary scouring and gravitational wave recoil in massive elliptical galaxies

Nader Khonji, Alessia Gualandris, Justin I. Read +1

Scouring by supermassive black hole (SMBH) binaries is the most accepted mechanism for the formation of the cores seen in giant elliptical galaxies. However, an additional mechanis…

EDGE: Dark matter core creation depends on the timing of star formation

Claudia Muni, Andrew Pontzen, Justin I. Read +5

We study feedback-driven cold dark matter core creation in the EDGE suite of radiation-hydrodynamical dwarf galaxy simulations. Understanding this process is crucial when using obs…

The PARADIGM project I: How early merger histories shape the present-day sizes of Milky-Way-mass galaxies

Gandhali D. Joshi, Andrew Pontzen, Oscar Agertz +3

How mergers affect galaxy formation depends on both feedback processes, and on the geometry and strength of the mergers themselves. We introduce the PARADIGM project, where we stud…

EDGE: A new model for Nuclear Star Cluster formation in dwarf galaxies

Emily I. Gray, Justin I. Read, Ethan Taylor +8

Nuclear Star Clusters (NSCs) are amongst the densest stellar systems in the Universe and are found at the centres of many bright spiral and elliptical galaxies, and up to 4…

Dwarf galaxies imply dark matter is heavier than

Tim Zimmermann, James Alvey, David J. E. Marsh +2

It is widely established that a lower bound on the dark matter particle mass, , can be obtained by demanding that the de Broglie wavelength in a given galaxy must be smaller tha…
