EDGE: Two routes to dark matter core formation in ultra-faint dwarfs
Matthew D. A. Orkney, Justin I. Read, Martin P. Rey +6
In the standard Lambda cold dark matter paradigm, pure dark matter simulations predict dwarf galaxies should inhabit dark matter haloes with a centrally diverging density `cusp'. T…
Formation of the largest galactic cores through binary scouring and gravitational wave recoil
Imran Nasim, Alessia Gualandris, Justin I. Read +3
Massive elliptical galaxies are typically observed to have central cores in their projected radial light profiles. Such cores have long been thought to form through `binary scourin…
Defeating stochasticity: coalescence timescales of massive black holes in galaxy mergers
Imran Nasim, Alessia Gualandris, Justin Read +3
The coalescence of massive black hole binaries (BHBs) in galactic mergers is the primary source of gravitational waves (GWs) at low frequencies. Current estimates of GW detection r…
Uncovering the Orbit of the Hercules Dwarf Galaxy
Alexandra L. Gregory, Michelle L. M. Collins, Denis Erkal +6
We present new chemo--kinematics of the Hercules dwarf galaxy based on Keck II-- DEIMOS spectroscopy. Our 21 confirmed members have a systemic velocity of $v_{\mathrm{Herc}}=46.4\p…
A Dwarf Disrupting -- Andromeda XXVII and the North West Stream
Janet Preston, Michelle L. M. Collins, Rodrigo A. Ibata +10
We present a kinematic and spectroscopic analysis of 38 red giant branch stars, in 7 fields, spanning the dwarf spheroidal galaxy Andromeda XXVII and the upper segment of the North…
An efficient positive potential-density pair expansion for modelling galaxies
Armando Rojas-Niño, Justin I. Read, Luis Aguilar +1
We present a novel positive potential-density pair expansion for modelling galaxies, based on the Miyamoto-Nagai (MN) disc. By using three sets of such discs, each one of them alig…
