OH and H2O maser variations in W33B
P. Colom, E. E. Lekht, M. I. Pashchenko +1
The active star-forming region W33B is a source of OH and H2O maser emission located in distinct zones around the central object. The aim was to obtain the complete Stokes pattern…
The chemical diversity of comets
J. Crovisier, N. Biver, D. Bockelée-Morvan +3
A fundamental question in cometary science is whether the different dynamical classes of comets have different chemical compositions, which would reflect different initial conditio…
Molecular composition of comet 46P/Wirtanen from millimetre-wave spectroscopy
N. Biver, D. Bockelée-Morvan, J. Boissier +11
We present the results of a molecular survey of comet 46P/Wirtanen undertaken with the IRAM 30-m and NOEMA radio telescopes in December 2018. Observations at IRAM 30-m during the 1…
On sky characterization of the BAORadio wide band digital backend: Search for HI emission in Abell85, Abell1205 and Abell2440 galaxy clusters
R. Ansari, J. E Campagne, P. Colom +5
We have observed regions of three galaxy clusters at z [0.06, 0.09] (Abell85, Abell1205, Abell2440), as well as calibration sources with the Nancay radiotelescope (NRT) to se…
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…
A ridge of recent massive star formation between Sgr B2M and Sgr B2N
P. de Vicente, J. Martin-Pintado, R. Neri +1
We present single dish and interferometric maps of several rotational transitions of HC3N vibrationally excited levels towards Sgr B2. The single dish maps show, for the first time…
