A DEEP Chandra CATALOG OF X-RAY POINT SOURCES TOWARD THE GALACTIC CENTER
We present a catalog of 2357 point sources detected during 590 ks of Chandra observations of the 17-by-17 arcminute field around Sgr A. This field encompasses a physical area of 40 by 40 pc at a distance of 8 kpc. The completeness limit of the sample at the Galactic center is 10 erg s (2.0–8.0 keV), while the detection limit is an order of magnitude lower. The 281 sources detected below 1.5 keV...
متن کاملA CATALOG OF 24μm SOURCES TOWARD THE GALACTIC CENTER
We present a ∼ 1.5 × 8 (220×1195pc) Multiband Imaging Photometer for Spitzer 24μm image of the Galactic Center and an accompanying point source list. This image is the highest spatial resolution (6 ∼ 0.25pc) and sensitivity map ever taken across the GC at this wavelength, showing the emission by warm dust in unprecedented detail. Over 120,000 point sources are identified in this catalog with si...
متن کاملDetection of HCOOCH3 toward a Low-Mass Protostar, NGC 1333 IRAS 4B
The rotational spectral lines of methylformate (HCOOCH3) have been detected toward a low-mass protostar, NGC 1333 IRAS 4B, with the Nobeyama 45m radio telescope. The column density is derived to be (7–37)× 1015 cm−2, assuming a source size of 1′′ and the range of the excitation temperature to be from 50K to 200K. The column density is almost comparable to those found in other low-mass star-form...
متن کاملThe molecular outflows in NGC 1333
We present the results of CO(J =3→2) mapping using the James Clerk Maxwell Telescope of the active star formation region NGC 1333, supplemented by CO(J=1→0) mapping from the Onsala Space Observatory millimetre telescope. These maps provide a detailed overview of the complex cluster of overlapping molecular outflows associated with Herbig-Haro (HH) objects and shocked H2, and the far-infrared an...
متن کاملCores and cavities in NGC 1333
We present 1.3mm continuum and CS J = 5 → 4 maps at 12′′ resolution of the NGC1333 star forming region. The area covered is 8′ × 6′. The large-scale bolometer and CS maps delineate very nicely the large central cavity together with the cores situated in the surrounding compressed shell. In addition to the four dust cores IRAS4A-B, IRAS2 and SVS13, we discovered two fainter condensations, one of...
