Extreme X-ray Behavior in the Low-Luminosity Active Nucleus of NGC 4395

E. C. Moran, M. Eracleous, K. M. Leighly +4

We present the results of a 17 ks Chandra observation of the nearby dwarf spiral galaxy NGC 4395, focusing on the X-ray properties of the moderate-mass black hole that resides in i…

The Chandra Deep Field North Survey. VIII. X-ray Constraints on Spiral Galaxies from 0.4 < z < 1.5

A. E. Hornschemeier, W. N. Brandt, D. M. Alexander +5

We present a statistical X-ray study of spiral galaxies in the Hubble Deep Field-North and its Flanking Fields using the Chandra Deep Field North 1 Ms dataset. We find that approxi…

Simulating CCDs for the Chandra Advanced CCD Imaging Spectrometer

L. K. Townsley, P. S. Broos, G. Chartas +3

We have implemented a Monte Carlo algorithm to model and predict the response of various kinds of CCDs to X-ray photons and minimally-ionizing particles and have applied this model…

X-ray Spectroscopy of QSOs with Broad Ultraviolet Absorption Lines

S. C. Gallagher, W. N. Brandt, G. Chartas +1

For the population of QSOs with broad ultraviolet absorption lines, we are just beginning to accumulate X-ray observations with enough counts for spectral analysis at CCD resolutio…

Three LINERs Under the Chandra X-Ray Microscope

M. Eracleous, J. C. Shields, G. Chartas +1

We use X-ray observations of three galaxies hosting LINERs (NGC 404, NGC 4736, NGC 4579) with Chandra to study their power sources. We find very diverse properties within this smal…

Constraining H0 from Chandra Observations of Q0957+561

G. Chartas, V. Gupta, G. Garmire +4

We report the detection of the lens cluster of the gravitational lens (GL) system Q0957+561 from a deep observation with the Advanced CCD Imaging Spectrometer on-board the Chandra…
