A Photoevaporating Rotating Disk in the Cepheus a Hw2 Star Cluster
We present VLA and PdBI subarcsecond images (∼0.15 ′′-0.6 ′′) of the radiocontinuum emission at 7 mm and of the SO 2 lines toward the Cepheus A HW2 region. The SO 2 images reveal the presence of a hot core internally heated by an intermediate mass protostar, and a circumstellar rotating disk around the HW2 radio jet with size 600 AU×100 AU and mass of ∼1 M ⊙. Keplerian rotation for the disk vel...
متن کاملExpansion of the R4 H2o Maser Arc near Cepheus a Hw2
We present new (April 2000) MERLIN observations of the H2O masers located near the protostar Cepheus A HW2. The MERLIN observations detect many of the structures found in earlier (1996) VLBA observations of Torrelles and collaborators, and the changed positions of these structures are compatible with the VLBA proper motions and astrometric uncertainties. The radius of curvature of the R4 struct...
متن کاملUnveiling the Main Heating Sources in the Cepheus a Hw2 Region
We present high angular resolution PdBI images (beam of ∼0.33) of the J=27→26 line from several vibrational levels (v7=1 and v6=1) of HC3N toward Cepheus A HW2. These images reveal the two main heating sources in the cluster: one centered in the disk collimating the HW2 radio jet (the HW2 disk), and the other associated with a hot core 0.3 northeast HW2 (the HC). This is the first time that vib...
متن کاملA Model For Infall Around Virialized Halos
Motivated by the recent direct detection of cosmological gas infall, we develop an analytical model for calculating the mean density profile around an initial overdensity that later forms a dark matter halo. We account for the problem of peaks within peaks; when considering a halo of a given mass we ensure that this halo is not a part of a larger virialized halo. For halos that represent high-s...
متن کاملExtra-planar Diffuse Hot Gas Around Normal Disk Galaxies
I review results from Chandra observations of nearby normal edge-on galaxies (Sd to Sa types). These galaxies have a broad range of star formation rate, but none of them is dominated by a nuclear starburst. The galaxies are all in directions of low Galactic foreground absorption (NHI ∼ < 4 × 10 cm). Extra-Planar diffuse soft X-ray emission is detected unambiguously from all the galaxies, except...
