21 cm observation of LSS at z~1 Instrument sensitivity and foreground subtraction
R. Ansari, J. E. Campagne, P. Colom +6
Large Scale Structures (LSS) in the universe can be traced using the neutral atomic hydrogen HI through its 21cm emission. Such a 3D matter distribution map can be used to test the…
BAORadio : Cartographie 3D de la distribution de gaz H dans l'Univers
R. Ansari, J. E. Campagne, P. Colom +5
3D mapping of matter distribution in the universe through the 21 cm radio emission of atomic hydrogen is a complementary approach to optical surveys for the study of the Large Scal…
HESS J1943+213: a candidate extreme BL Lacertae object
H. E. S. S. Collaboration, :, A. Abramowski +200
We report on a newly detected point-like source, HESS J1943+213 located in the Galactic plane. This source coincides with an unidentified hard X-ray source IGR J19443+2117, which w…
Molecular investigations of comets C/2002 X5 (Kudo-Fujikawa), C/2002 V1 (NEAT), and C/2006 P1 (McNaught) at small heliocentric distances
N. Biver, D. Bockelée-Morvan, P. Colom +4
We present unique spectroscopic radio observations of comets C/2002 X5 (Kudo-Fujikawa), C/2002 V1 (NEAT), and C/2006 P1 (McNaught), which came within $r_h ~ 0.2 AU of the Sun in 20…
Earth-based detection of the millimetric thermal emission of the nucleus of comet 8P/Tuttle
J. Boissier, O. Groussin, L. Jorda +7
Little is known about the physical properties of cometary nuclei. Apart from space mission targets, measuring the thermal emission of a nucleus is one of the few means to derive it…
