Near-IR clumps and their properties in high-z galaxies with JWST/NIRCam

Boris S. Kalita, John D. Silverman, Emanuele Daddi +3

Resolved stellar morphology of galaxies was inaccessible before JWST. This limitation, due to the impact of dust on rest-frame UV light, had withheld major observational conc…

The Chandra-COSMOS survey IV: X-ray spectra of the bright sample

G. Lanzuisi, F. Civano, M. Elvis +14

We present the X-ray spectral analysis of the 390 brightest extragalactic sources in the Chandra-COSMOS catalog, showing at least 70 net counts in the 0.5-7 keV band. This sample h…

The Galactic Center: A Laboratory for Fundamental Astrophysics and Galactic Nuclei

A. Ghez, M. Morris, J. Lu +24

As the closest example of a galactic nucleus, the Galactic center presents an exquisite laboratory for learning about supermassive black holes (SMBH) and their environs. Detailed s…

The X-ray and Radio Connection in Low-luminosity Active Nuclei

F. Panessa, X. Barcons, L. Bassani +4

We present the results of the correlation between the nuclear 2-10 keV X-ray and radio (at 2cm, 6cm and 20cm) luminosities for a well defined sample of local Seyfert galaxies. We u…

Multi-wavelength and black hole mass properties of Low Luminosity Active Nuclei

F. Panessa, L. Bassani, M. Cappi +6

We investigate the relation between the X-ray nuclear emission, optical emission line, radio luminosity and black hole mass for a sample of nearby Seyfert galaxies. Strong linear c…

X-ray Properties of Intermediate-mass Black Holes in Active Galaxies

Jenny E. Greene, Luis C. Ho

We present a pilot study of the X-ray properties of intermediate-mass (~10^5-10^6 M_sun) black holes in active galaxies using the Chandra X-ray telescope. Eight of the 10 active ga…
