Measuring monster MBHs: maybe mighty, maybe merely massive
M. Gliozzi, A. Akylas, J. K. Williams +1
Accurate black hole mass (MBH) measurements in high-z galaxies are difficult yet crucial to constrain the growth of supermassive BHs, and to discriminate between competing BH seed…
Comparing indirect methods for black hole masses in AGN: the good, the bad, and the ugly
M. Gliozzi, J. K. Williams, A. Akylas +4
The black hole mass MBH is crucial in constraining the growth of supermassive BHs within their host galaxies. Since direct measurements of MBH with dynamical methods are restricted…
FRAMEx. V. Radio Spectral Shape at Central Sub-parsec Region of AGNs
Onic I. Shuvo, Megan C. Johnson, Nathan J. Secrest +4
We present results from the Very Long Baseline Array (VLBA) multi-frequency (1.6, 4.4, 8.6, 22 GHz), high-sensitivity (~25 microJy beam^-1), sub-parsec scale (<1 pc) observations a…
Exploring X-ray Properties of Low Metallicity Dwarf Galaxies
Jenna M. Cann, Kimberly A. Weaver, Ryan W. Pfeifle +3
One of the primary outstanding questions in extragalactic astronomy is the formation and early evolution of the supermassive black holes that are seen in nearly every massive galax…
NuSTAR Observations of Four Mid-IR Selected Dual AGN Candidates in Galaxy Mergers
Ryan W. Pfeifle, Kimberly Weaver, Shobita Satyapal +5
Mergers of galaxies are a ubiquitous phenomenon in the Universe and represent a natural consequence of the ``bottom-up'' mass accumulation and galaxy evolution cosmological paradig…
Assessing indirect methods to determine black hole masses using NGC 4151
James K. Williams, Mario Gliozzi, Kyle A. Bockwoldt +1
Accurately determining the black hole mass () in active galactic nuclei (AGN) is crucial to constraining their properties and to studying their evolution. While dire…
