Fermi-LAT Discovery of GeV Gamma-Ray Emission from the Young Supernova Remnant Cassiopeia A
(IOP Publishing, 2010-02)
We report on the first detection of GeV high-energy gamma-ray emission from a young supernova remnant (SNR) with the Large Area Telescope aboard the Fermi Gamma-ray Space Telescope. These observations reveal a source with ...
Deep Morphological and Spectral Study of the SNR RCW 86 with Fermi-LAT
(Iop Publishing, 2016-03)
RCW 86 is a young supernova remnant (SNR) showing a shell-type structure at several wavelengths and is thought to be an efficient cosmic-ray (CR) accelerator. Earlier Fermi Large Area Telescope results reported the detection ...
A Turbulent Origin for the Complex Envelope Kinematics in the Young Low-mass Core Per-bolo 58
(IOP Publishing, 2017-11)
We use CARMA 3 mm continuum and molecular lines (NH2D, N2H+, HCO+, HCN, and CS) at ∼1000 au resolution to characterize the structure and kinematics of the envelope surrounding the deeply embedded first core candidate ...
On the origin of two unidentified radio/X-ray sources discovered with XMM-Newton
(EDP Sciences, 2015-12)
Aims. We aim at clarifying the nature of the emission of two spatially related unidentified X-ray sources detected with XMM−Newton telescope at intermediate-low Galactic latitude Methods. We use the imaging and spectral ...
Optical multicolor polarization observations in the region of the open cluster NGC 5749
(EDP Sciences, 2007-12)
We present (UBVRI) multicolor linear polarimetric data for 31 of the brightest stars in the area of the open cluster NGC 5749 considered to study the properties of the interstellar medium (ISM) towards the cluster. Our ...
The GRAVITY young stellar object survey VII. The inner dusty disks of T Tauri stars
(EDP Sciences, 2021)
Context. T Tauri stars are surrounded by dust and gas disks. As material reservoirs from which matter is accreted onto the central star
and planets are built, these protoplanetary disks play a central role in star and ...
Optical polarization study in the open cluster NGC 6250
(Wiley Blackwell Publishing, Inc, 2008-11)
We present (UBVRI) multicolour linear polarimetric data for 32 of the brightest stars in the area of the open cluster NGC 6250, with the aim of studying the properties of the interstellar medium (ISM) towards the cluster. ...
Optical Polarization Observations of NGC 6231: Evidence for a Past Supernova Fingerprint
(IOP Publishing, 2003-11)
We present the first linear multicolor polarization observations for a sample of 35 stars in the direction of the Galactic cluster NGC 6231. We have found a complex pattern in the angles of the polarimetric vectors. Near ...
A compact dual-loop antenna with radial wires
(2011)
New Antenna geometries are continuously proposed by engineers and researchers in order to meet increasingly demanding characteristics of wireless communication systems. In this document a compact wire antenna consisting ...
