Far-Ultraviolet & Halpha Spectroscopy of SNR0057-7226 in the SMC HII Region N66
Charles Danforth, Ravi Sankrit, William Blair +2
N66/NGC346 is the largest and brightest HII region in the Small Magellanic Cloud and contains at least one known supernova remnant SNR0057-7226. Optical emission from the remnant i…
Asymptotics of almost holomorphic sections of ample line bundles on symplectic manifolds: an addendum
B. Shiffman, S. Zelditch
We define a Gaussian measure on the space of almost holomorphic sections of powers of an ample line bundle over a symplectic manifold , and calculate th…
Stellar population gradients in Seyfert 2 galaxies
Thaisa Storchi-Bergmann, Daniel I. Raimann, R. Gonzalez Delgado +4
We study the variation of the stellar population properties as a function of distance from the nucleus for a sample of 35 Seyfert 2 galaxies using the technique of stellar populati…
SkyQuery: A WebService Approach to Federate Databases
Tanu Malik, Alex S. Szalay, Tamas Budavari +1
Traditional science searched for new objects and phenomena that led to discoveries. Tomorrow's science will combine together the large pool of information in scientific archives an…
New {\it Chandra} Results on Seyfert I galaxies: Fe-K lines
U. Padmanabhan, T. Yaqoob
We present measurements of the Fe-K line for nine Seyfert I galaxies using Chandra High Energy Transmission Grating Spectrometer (HETGS) data. The centroid energies are narrowly di…
New Chandra/HST-STIS results on Seyfert I AGN: Photoionized Outflows
B. McKernan, T. Yaqoob
We present soft X-ray results from observations with the Chandra HETGS of the Seyfert I AGN NGC 4593 and Mrk 509. We discuss the photoionized outflows associated with Seyfert I AGN…
