Design, operation and performance of the PAON4 prototype transit interferometer
R. Ansari, J. E Campagne, D. Charlet +14
PAON4 is an L-band (1250-1500 MHz) small interferometer operating in transit mode deployed at the Nançay observatory in France, designed as a prototype instrument for Intensity Map…
Progress in the Construction and Testing of the Tianlai Radio Interferometers
Santanu Das, Christopher J. Anderson, Reza Ansari +44
The Tianlai Pathfinder is designed to demonstrate the feasibility of using a wide field of view radio interferometers to map the density of neutral hydrogen in the Universe after t…
BAORadio: A digital pipeline for radio interferometry and 21 cm mapping of large scale structures
Réza Ansari, Jean-Eric Campagne, Pierre Colom +5
3D mapping of matter distribution in the universe through the 21 cm radio emission of atomic hydrogen HI is a complementary approach to optical surveys for the study of the Large S…
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…

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…
Kinematics of the Local Universe XIII. 21-cm line measurements of 452 galaxies with the Nançay radiotelescope, JHK Tully-Fisher relation and preliminary maps of the peculiar velocity field
Gilles Theureau, Mikko Hanski, Nicole Coudreau +2
This paper presents 452 new 21-cm neutral hydrogen line measurements carried out with the FORT receiver of the meridian transit Nançay radiotelescope (NRT) in the period April 2003…
H.E.S.S. observations of the Galactic Center region and their possible dark matter interpretation
H. E. S. S. collaboration, :, F. A. Aharonian
The detection of gamma-rays from the source HESS J1745-290 in the Galactic Center (GC) region with the H.E.S.S. array of Cherenkov telescopes in 2004 is presented. After subtractio…
HS 0837+4717 -- a metal-deficient blue compact galaxy with large nitrogen excess
Simon Pustilnik, Alexei Kniazev, Alexander Pramskij +5
(Abridged) We present the results of high S/N long-slit spectroscopy with the Multiple Mirror and the SAO 6-m telescopes, optical imaging with the Wise 1-m telescope and HI observa…
