The Highest Resolution Chandra View of Photoionization and Jet-Cloud Interaction in the Nuclear Region of NGC 4151
Junfeng Wang, G. Fabbiano, M. Karovska +4
We report high resolution imaging of the nucleus of the Seyfert 1 galaxy NGC 4151 obtained with a 50 ks Chandra HRC observation. The HRC image resolves the emission on spatial scal…
A strong excess in the 20-100 keV emission of NGC 1365
G. Risaliti, V. Braito, V. Laparola +8
We present a new Suzaku observation of the obscured AGN in NGC 1365, revealing an unexpected excess of X-rays above 20 keV of at least a factor ~2 with respect to the extrapolation…
AGN/starburst connection in action: the half million second RGS spectrum of NGC1365
M. Guainazzi, G. Risaliti, A. Nucita +4
We present a deep (~5.8 days) 0.3-2 keV high-resolution spectrum of NGC1365, collected with the reflection grating spectrometer (RGS) on board XMM-Newton. The spectrum is dominated…
Protoplanetary Disk Evolution around the Triggered Star Forming Region Cepheus B
Konstantin V. Getman, Eric D. Feigelson, Kevin L. Luhman +3
The Cepheus B (CepB) molecular cloud and a portion of the nearby CepOB3b OB association, one of the most active regions of star formation within 1 kpc, have been observed with the…
A Chandra Study of the Rosette Star-Forming Complex. II. Clusters in the Rosette Molecular Cloud
Junfeng Wang, Eric D. Feigelson, Leisa K. Townsley +3
We explore here the young stellar populations in the Rosette Molecular Cloud (RMC) region with high spatial resolution X-ray images from the Chandra X-ray Observatory, which are ef…
Young stellar clusters and star formation throughout the Galaxy
Eric Feigelson, Fred Adams, Lori Allen +22
Most stars are born in rich young stellar clusters (YSCs) embedded in giant molecular clouds. The most massive stars live out their short lives there, profoundly influencing their…
