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 (BH) mass-stellar mass () plane encodes both the integrated growth of galaxies and their central black holes, a…
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…
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. Sel…
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…
Not all cores are equal: Phase-space origins of dynamical friction, stalling and buoyancy
Shashank Dattathri, Frank C. van den Bosch, Uddipan Banik +4
Dynamical friction governs the orbital decay of massive perturbers within galaxies and dark matter halos, yet its standard Chandrasekhar formulation fails in systems with cores of…
Revisiting Galaxy Cluster Scaling Relations through Dark Matter-Gas Coherence: Scatter Dependence on Dynamical State
Giulia Cerini, Elena Bellomi, Nico Cappelluti +4
Galaxy clusters, the most massive, dark-matter-dominated, and most recently assembled structures in the Universe, are key tools for probing cosmology. However, uncertainties in sca…
The Roman View of Strong Gravitational Lenses
Bryce Wedig, Tansu Daylan, Simon Birrer +13
Galaxy-galaxy strong gravitational lenses can constrain dark matter models and the Lambda Cold Dark Matter cosmological paradigm at sub-galactic scales. Currently, there is a deart…
A luminous and hot infrared through X-ray transient at a 5 kpc offset from a dwarf galaxy
Jean J. Somalwar, Vikram Ravi, Raffaella Margutti +20
We are searching for hot, constant-color, offset optical flares in the Zwicky Transient Facility (ZTF) data stream that are from any galaxy in public imaging data from th…
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…
The rise of the galactic empire: luminosity functions at and estimated with the MIDISNGDEEP ultra-deep JWST/NIRCam dataset
Pablo G. Pérez-González, Göran Östlin, Luca Costantin +39
We present a sample of six F200W and three F277W dropout sources identified as galaxy candidates using the deepest JWST/NIRCam data to date (5 depths mag at…
Rates of Stellar Tidal Disruption Events around Intermediate-Mass Black Holes
Janet N. Y. Chang, Lixin Dai, Hugo Pfister +2
Rates of stellar tidal disruption events (TDEs) around supermassive black holes (SMBHs) have been extensively calculated using the loss cone theory, while theoretical work on TDE r…
Forecasting Galaxy Cluster HI Mass Recovery with CHIME at Redshifts z = 1 and 2 via the IllustrisTNG Simulations
Ava Polzin, Laura Newburgh, Priyamvada Natarajan +1
The Canadian Hydrogen Intensity Mapping Experiment (CHIME) is a drift-scan interferometer designed to map the entire northern sky every 24 hours. The all-sky coverage and sensitivi…
