RadioAstron -- a Telescope with a Size of 300 000 km: Main Parameters and First Observational Results
N. S. Kardashev, V. V. Khartov, RadioAstron collaboration
The Russian Academy of Sciences and Federal Space Agency, together with the participation of many international organizations, worked toward the launch of the RadioAstron orbiting…
Towards the Event Horizon - The Vicinity of AGN at Micro-Arcsecond Resolution
T. P. Krichbaum, D. A. Graham, W. Alef +18
We summarize the present status of VLBI experiments at 3 mm (86 GHz), 2 mm (129-150 GHz) and 1.3 mm (215-230 GHz). We present and discuss a new 3 mm VLBI map of M87 (Virgo A), whic…
A Study of Cosmic Ray Secondaries Induced by the Mir Space Station Using AMS-01
01 Collaboration
The Alpha Magnetic Spectrometer (AMS-02) is a high energy particle physics experiment that will study cosmic rays in the to range and will…
A multifrequency analysis of radio variability of blazars
A. Ciaramella, C. Bongardo, H. D. Aller +9
We have carried out a multifrequency analysis of the radio variability of blazars, exploiting the data obtained during the extensive monitoring programs carried out at the Universi…
VLBI observations at 147 GHz: first detection of transatlantic fringes in bright AGN
T. P. Krichbaum, D. A. Graham, W. Alef +21
At 147 GHz (2mm wavelength), we detected three prominent AGN (NRAO150, 3C279, 1633+382) with Very Long Baseline Interferometry (VLBI) with an angular resolution of only 18 micro-ar…
Protons in near earth orbit
AMS Collaboration
The proton spectrum in the kinetic energy range 0.1 to 200 GeV was measured by the Alpha Magnetic Spectrometer (AMS) during space shuttle flight STS-91 at an altitude of 380 km. Ab…
Search for antihelium in cosmic rays
AMS Collaboration
The Alpha Magnetic Spectrometer (AMS) was flown on the space shuttle Discovery during flight STS-91 in a 51.7 degree orbit at altitudes between 320 and 390 km. A total of 2.86 * 10…
