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…
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…
Too Quiet for Comfort: Local Little Red Dots Lack Variability over Decades
Colin J. Burke, Zachary Stone, Yue Shen +1
Several local () metal-poor dwarf AGNs have remarkably similar properties to those of high-redshift Little Red Dots (LRDs), and are recently proposed to be local ana…
DeepDISC-photoz: Deep Learning-Based Photometric Redshift Estimation for Rubin LSST
Grant Merz, Xin Liu, Samuel Schmidt +11
Photometric redshifts will be a key data product for the Rubin Observatory Legacy Survey of Space and Time (LSST) as well as for future ground and space-based surveys. The need for…
TESS photometry of the nova eruption in V606 Vul: asymmetric photosphere and multiple ejections?
Kirill V. Sokolovsky, Elias Aydi, Konstantin Malanchev +70
Lightcurves of many classical novae deviate from the canonical "fast rise - smooth decline" pattern and display complex variability behavior. We present the first TESS-space-photom…
