Intermediate Mass Black Hole Binary Evolution in Nuclear Star Clusters: the effect of the stellar mass black hole population
Fazeel Mahmood Khan, Peter Berczik, Margarita Sobolenko +4
In this study, we investigate the dynamics of Intermediate-Mass Black Hole (IMBH) binaries within Nuclear Star Clusters (NSCs) that contain a population of stellar-mass black holes…
JWST Observations of the Double Nucleus in NGC 4486B: Possible Evidence for a Recent Binary SMBH Merger and Recoil
Behzad Tahmasebzadeh, Monica Valluri, Shashank Dattathri +19
A recent study of the compact elliptical galaxy NGC 4486B using JWST-NIRSpec IFU kinematics confirmed a supermassive black hole (SMBH) of mass (~8% of…
Beyond single tracers: CNN-based inference of galaxy mass profiles from combined gas and stellar kinematics
Julen Expósito-Márquez, Arianna Di Cintio, Chris Brook +2
We investigate whether combining gas and stellar kinematic maps provides measurable advantages in recovering galaxy mass profiles, compared to using single-component maps alone. Wh…
1FLAT: a Firmamento-based catalog of AGN in Fermi-LAT high Galactic latitude γ-ray sources
P. Giommi, M. Doro, M. Gouvêa +15
We present a systematic reassessment of 5,062 high-Galactic latitude gamma-ray sources from the Fermi-LAT 4FGL-DR4 catalog using Firmamento, a web-based platform for multi-frequenc…
Handy Relation Between Binary Black Hole Merger Times and Host Galaxy Properties
Kelly Holley-Bockelmann, Fazeel Khan, Isaiah Williams +6
Over the past 15 years, the evidence has clearly demonstrated that massive black hole (MBH) binary merger timescales depend strongly on the structural and kinematic properties of t…
Causal evidence for the primordiality of colours in trans-Neptunian objects
Benjamin L. Davis, Mohamad Ali-Dib, Yujia Zheng +3
The origins of the colours of Trans-Neptunian Objects (TNOs) represent a crucial unresolved question, central to understanding the history of our Solar System. Recent observational…

Benjamin L. Davis, Mohamad Ali-Dib, Yujia Zheng +3
The origins of the colors of Trans-Neptunian Objects (TNOs) represent a crucial unresolved question, central to understanding the history of our Solar System. Recent observational…
AGN Feedback-Induced Stellar Density Expansion in the Inner Regions of Early-Type Galaxies
Fazeel Mahmood Khan, Ángel Rodríguez, Andrea V. Macciò +1
Observations indicate that early-type galaxies exhibit varying slopes in the relation between their central stellar surface density and stellar mass (). Low-mass g…
A physically motivated galaxy size definition across different state-of-the-art hydrodynamical simulations
Elena Arjona-Galvez, Salvador Cardona-Barrero, Robert J. J. Grand +6
Galaxy sizes are a key parameter to distinguishing between different galaxy types and morphologies, reflecting their formation and assembly histories. Several methods define galaxy…
Are Gas-rich Ultra-diffuse Galaxies and Field Dwarfs Distinct?
Khadeejah Motiwala, Ananthan Karunakaran, Kristine Spekkens +5
We explore the differences in gas-rich field Ultra-Diffuse Galaxies (UDGs) and classical dwarf galaxies using an extensive atomic gas (HI) follow-up survey of optically-selected UD…
