Rapid Growth of Intermediate-Mass Black Holes through Disk-induced Stellar Disruptions
Mengye Wang, Yiqiu Ma, Qingwen Wu +3
Dense nuclear star clusters provide unique environments for studying the dynamical interactions between stars and massive black holes. When an accretion disk is present, dissipativ…
Linking high-mass X-ray binaries to binary compact object mergers in Milky Way-like galaxies
Felipe Vivanco Cádiz, M. Celeste Artale, Nicola Masetti +5
High-mass X-ray binaries (HMXBs) constitute a potential intermediate phase connecting massive stellar binaries to the formation of coalescing binary compact objects (BCOs). Yet, th…
Black hole populations and hierarchical growth across the AGN parameter space
Maria Paola Vaccaro, Michela Mapelli, Alessandro Alberto Trani +1
Active galactic nuclei (AGNs) have been proposed as efficient environments for the formation of binary black holes (BBHs). We present an updated semi-analytical framework for BBH f…
Towards A Universal Analytical Model of Population III Star Formation: A Bridge Between Cosmological Scales and Protostars
James Gurian, Boyuan Liu, Donghui Jeong +4
We construct an analytical model of Population III star formation that connects the cosmological radiation background to sub-AU protostellar disk fragmentation, a dynamic range ina…
Impact of Stochastic Pop~III X-ray Binaries on the Cosmological 21-cm Signal
Saswata Dasgupta, Boyuan Liu, Anastasia Fialkov +3
High-mass X-ray binaries are one of the primary drivers of the 21-cm signal from Cosmic Dawn and Reionization, playing a leading role in the thermal history of the intergalactic me…
Direct N-body simulations of rotating and extremely massive Population III star clusters
Kai Wu, Ataru Tanikawa, Francesco Flammini Dotti +6
Aims. We present eight direct N-body simulations with NBODY6++GPU of extremely massive, initially rotating Population III star clusters with 1.01 x 10^5 stars. Methods. Our models…
The Cliff: A Metal-Poor Little Red Dot Hosting an Overmassive Black Hole at
Lucy R. Ivey, Francesco D'Eugenio, Roberto Maiolino +18
JWST has revealed a large population of massive black holes (BHs) in the early Universe with unusual properties which mark them as distinct from low-redshift active galactic nuclei…
Population synthesis of Be X-ray binaries in the Small Magellanic Cloud: Angular momentum recycling and stable mass transfer
Víctor López Oller, Boyuan Liu, Michela Mapelli +5
Be X-ray binaries (BeXRBs) are key laboratories to constrain binary interaction processes such as mass transfer, angular-momentum transport, and natal kicks. The Small Magellanic C…
An Analytic Model of Gravitational Collapse Induced by Radiative Cooling: Instability Scale, Infall Velocity, and Accretion Rate
James Gurian, Boyuan Liu, Donghui Jeong +3
We present an analytic description of the spherically symmetric gravitational collapse of radiatively cooling gas clouds, which illustrates the mechanism by which radiative cooling…
Towards a universal analytical model for Population III star formation: interplay between feedback and fragmentation
Boyuan Liu, James Gurian, Kohei Inayoshi +4
JWST has brought us new insights into Cosmic Dawn with tentative detection of the unique signatures of metal-free Population III (Pop III) stars, such as strong HeII emission, extr…
Rapidly rotating Population III stellar models as a source of primary nitrogen
Sophie Tsiatsiou, Yves Sibony, Devesh Nandal +12
The first stars might have been fast rotators. This would have important consequences for their radiative, mechanical and chemical feedback. We discuss the impact of fast initial r…
RIGEL: Simulating dwarf galaxies at solar mass resolution with radiative transfer and feedback from individual massive stars
Yunwei Deng, Hui Li, Boyuan Liu +3
We introduce the RIGEL model, a novel framework to self-consistently model the effects of stellar feedback in the multiphase ISM of dwarf galaxies with radiative transfer (RT) on a…
Zero Metallicity with Zero CPU Hours: Masses of the First Stars on the Laptop
James Gurian, Donghui Jeong, Boyuan Liu
We develop an analytic model for the mass of the first stars forming in the center of primordial gas clouds as a function of host halo mass, redshift, and degree of rotation. The m…
