The Black Hole Occupation Fraction as a Fossil Record of Seeding, Dynamics, and Galaxy Assembly
Emma Jane Weller, Priyamvada Natarajan, Colin J. Burke
The black hole occupation fraction (BHOF) is a powerful but intrinsically layered diagnostic of massive black hole (BH) seeding and subsequent galaxy assembly. We measure the total…
Tracing black hole and galaxy growth across environments since cosmic noon
Emma Jane Weller, Priyamvada Natarajan, Colin J. Burke +1
The distribution of systems in the black hole mass-stellar mass () plane encodes not only the integrated growth of galaxies and their central black holes (BH…
Lensing-Reconstructed Dark Matter-Intracluster Medium Coherence as a Probe of Cluster Dynamical State: Application to HSTFF, RELICS, and CLASH Clusters
Giulia Cerini, Sayan Saha, Jacqueline McCleary +13
We present the first application of Fourier-space coherence analysis between the lensing-reconstructed projected mass distribution and the X-ray-emitting intracluster medium to a s…
Self-interacting dark matter promotes bar formation in disk galaxies
Shashank Dattathri, Frank C. van den Bosch, HanYuan Zhang +4
Despite its remarkable success on large scales, the standard CDM paradigm faces persistent small-scale challenges that have motivated alternative models for the dark sector. Se…
Strong LensIng and Cluster Evolution (SLICE) with JWST: Early Results, Lens Models, and High-Redshift Detections
Catherine Cerny, Guillaume Mahler, Keren Sharon +24
We leverage JWST's superb resolution to derive strong lensing mass maps of 14 clusters, spanning a redshift range of and a mass range of $M_{500}\sim2-12 \times…
Variability as a new discovery channel for Intermediate-Mass Black Holes in the Time Domain Era
Colin J. Burke, Priyamvada Natarajan
Between the groundbreaking detections of stellar-mass black holes by LIGO/Virgo/KAGRA and JWST's revelation of a surprisingly abundant population of supermassive black holes, one c…
