Initial mass function of intermediate mass black hole seeds [PDF]

open access: yes, 2014
We study the Initial Mass Function (IMF) and host halo properties of Intermediate Mass Black Holes (IMBH, 10^{4-6} Msun) formed inside metal-free, UV illuminated atomic cooling haloes (virial temperature T_vir > 10^4 K) either via the direct collapse of ...

Search for intermediate mass black hole binaries in the first observing run of Advanced LIGO [PDF]

open access: yes, 2017
During their first observational run, the two Advanced LIGO detectors attained an unprecedented sensitivity, resulting in the first direct detections of gravitational-wave signals produced by stellar-mass binary black hole systems.

Inferring Parameters of GW170502: The Loudest Intermediate-mass Black Hole Trigger in LIGO’s O1/O2 data [PDF]

open access: yesAstrophysical Journal, 2019
Gravitational wave (GW) measurements provide the most robust constraints of the mass of astrophysical black holes. Using state-of-the-art GW signal models and a unique parameter estimation technique, we infer the source parameters of the loudest marginal

An Intermediate-mass Black Hole Hidden behind Thick Obscuration

open access: yesThe Astrophysical Journal
Recent models suggest approximately half of all accreting supermassive black holes (SMBHs; M _BH ≳ 10 ^5 M _⊙ ) are expected to undergo intense growth phases behind Compton-thick ( N _H > 1.5 × 10 ^24 cm ^−2 ) veils of obscuring gas.

Gravitational Waves and Intermediate-mass Black Hole Retention in Globular Clusters [PDF]

open access: yes, 2017
The recent discovery of gravitational waves (GWs) has opened new horizons for physics. Current and upcoming missions, such as LIGO, VIRGO, KAGRA, and LISA, promise to shed light on black holes of every size from stellar mass (SBH) sizes up to ...

Achieving Large and Anisotropic Spin‐Mediated Thermal Transport in Textured Quantum Magnets

open access: yesAdvanced Functional Materials, Volume 35, Issue 12, March 18, 2025.
An advanced solvent‐cast cold pressing method is developed to synthesize highly textured quantum magnets. By aligning spin chains in Ca2CuO3 perpendicular to the pressing direction, a spin‐mediated thermal conductivity of 10 ± 1 W m⁻¹ K⁻¹ is achieved, the highest reported for polycrystalline quantum materials.

The Fundamental Signature of Star Formation Quenching from AGN Feedback: A Critical Dependence of Quiescence on Supermassive Black Hole Mass, Not Accretion Rate

open access: yesThe Astrophysical Journal, 2023
We identify the intrinsic dependence of star formation quenching on a variety of galactic and environmental parameters, utilizing a machine-learning approach with Random Forest classification.
