Meteor induced ridge and trough formation and the structuring of the nighttime E-region ionosphere
Meteor induced ridge trough formation
2017/3/22
When meteor-generated plasma trails diffuse into the
ionosphere they create large ambipolar electric fields
mainly perpendicular to the Earth’s geomagnetic field
(B) and extending many kilometers f...
The XMM-Newton/Chandra monitoring campaign of the Galactic center region
Accretion accretion disks
2014/12/24
We present the first results of our X-ray monitoring campaign on a 1.7 square degree region centered on Sgr A* using the satellites XMM-Newton and Chandra. The purpose of this campaign is to monitor t...
Entrainment Mechanisms for Outflows in the L1551 Star-Forming Region
L1551 IRS5 formation
2014/12/24
We present high sensitivity 12CO and 13CO J=1!0 molecular line maps covering the full extent of the parsec scale L1551 molecular outflow, including the redshifted east-west (EW) flow. We also present ...
Kinematics of Protostellar Objects in the ρ Ophiuchus A Region
circumstellar matter clouds
2014/12/24
We present the detection of infall, rotation, and outflow kinematic signatures toward both a protostellar source, VLA 1623, and what was initially thought to be a pre-protostellar core, SM 1N, in the ...
High-Resolution Imaging of Warm and Dense Molecular Gas in the Nuclear Region of the Luminous Infrared Galaxy NGC 6240
formation interaction,
2014/12/23
We present ~2'' resolution CO (3-2), HCO+(4-3), and 880 μm continuum images of the luminous infrared galaxy NGC 6240 obtained at the Submillimeter Array. We find that the spatially resolved CO (3-2), ...
Discovery of a Molecular Outflow in the Haro 6-10 Star-forming Region
clouds jets and outfl ows
2014/12/23
We present high sensitivity 12CO and 13CO J=1!0 molecular line maps covering the full extent of the parsec scale Haro 6-10 Herbig-Haro (HH) flow. We report the discovery of a molecular CO outflow alon...
CIRCUMSTELLAR STRUCTURE AROUND EVOLVED STARS IN THE CYGNUS-X STAR FORMATION REGION
Cygnus-X star MIPS IRAC
2014/12/22
We present observations of newly discovered 24 micron circumstellar structures detected with the Multiband Imaging Photometer for Spitzer (MIPS) around three evolved stars in the Cygnus-X star forming...
Title: Properties of the Compact HII Region Complex G-0.02-0.07
extinction maps high-resolution
2014/12/20
Abstract: We present new extinction maps and high-resolution Paschen alpha images of G-0.02-0.07, a complex of compact HII regions located adjacent to the M-0.02-0.07 giant molecular cloud, 6 parsecs ...
TNOs are Cool: A survey of the trans-Neptunian region V. Physical characterization of 18 Plutinos using Herschel PACS observations
Kuiper belt objects Plutinos planetary systems observational photometric
2012/2/23
We present Herschel PACS photometry of 18 Plutinos and determine sizes and albedos for these objects using thermal modeling. We analyze our results for correlations, draw conclusions on the Plutino si...
Discovery of the correspondence between intra-cluster radio emission and a high pressure region detected through the Sunyaev-Zel'dovich effect
galaxies: clusters: individual: RX J1347-1145 – radio continuum: galaxies – X-rays: galaxies: clusters – cosmic back- ground radiation
2011/10/18
We analyzed new 237 MHz and 614 MHz GMRT data of the most X-ray luminous galaxy cluster, RX J1347-1145. Our radio results are compared with the MUSTANG 90 GHz Sunyaev-Zel'dovich effect map and with re...
Spectroscopic analysis of interaction between an EIT wave and a coronal upflow region
Spectroscopic analysis of interaction between an EIT wave and a coronal upflow region
2011/10/20
We report a spectroscopic analysis of an EIT wave event that occurred in active region 11081 on 2010 June 12 and was associated with an M2.0 class flare. The wave propagated near circularly. The south...
