Two Compton-Thick Active Nuclei in Arp 220?
Alessandro Paggi, Giuseppina Fabbiano, Guido Risaliti +2
Narrow-band spectral imaging with sub-pixel resolution of the Chandra-ACIS archival observation of the ULIRG merger Arp 220 strongly suggests two Compton thick nuclei, spatially co…
The Progression of Star Formation in the Rosette Molecular Cloud
Jason E. Ybarra, Elizabeth A. Lada, Carlos G. Román-Zúñiga +3
Using Spitzer Space Telescope and Chandra X-ray Observatory data, we identify YSOs in the Rosette Molecular Cloud (RMC). By being able to select cluster members and classify them i…
Fast and Furious: Shock Heated Gas as the Origin of Spatially Resolved Hard X-ray Emission in the Central 5 kpc of the Galaxy Merger NGC 6240
Junfeng Wang, Emanuele Nardini, Giuseppina Fabbiano +7
We have obtained a deep, sub-arcsecond resolution X-ray image of the nuclear region of the luminous galaxy merger NGC 6240 with Chandra, which resolves the X-ray emission from the…
The Exceptional Soft X-ray Halo of the Galaxy Merger NGC 6240
Emanuele Nardini, Junfeng Wang, Giuseppina Fabbiano +5
We report on a recent ~150-ks long Chandra observation of the ultraluminous infrared galaxy merger NGC 6240, which allows a detailed investigation of the diffuse galactic halo. Ext…
