Formation scenarios for the young stellar associations between galactic longitudes l = 280 ◦ − 360 ◦ ⋆

We investigate the spatial distribution, the space velocities and age distribution of the pre-main sequence (PMS) stars belonging to Ophiuchus, Lupus and Chamaeleon star-forming regions (SFRs), and of the young early-type star members of the Scorpius-Centaurus OB association. These young stellar associations extend over the galactic longitude range from 280◦ to 360◦, and are at a distance inter...

Stellar density distribution in the NIR on the Galactic plane at longitudes 15-27 deg. Clues for the Galactic bar ?

Garzón et al. (1997), López-Corredoira et al. (1999) and Hammersley et al. (2000) have identified in TMGS and DENIS data a large excess of stars at l=27◦ and b=0◦ which might correspond to an in-plane bar. We compared near infrared CAIN star counts and simulations from the Besançon Model of Galaxy on 15 fields between 15◦ and 45◦ in longitude and -2◦ and 2◦ in latitude. Comparisons confirm the ...

Evolution of the dark matter distribution at the galactic center.

Annihilation radiation from neutralino dark matter at the Galactic center (GC) would be greatly enhanced if the dark matter were strongly clustered around the supermassive black hole (SBH). The existence of a dark matter "spike" is made plausible by the observed, steeply rising stellar density near the GC SBH. Here the time-dependent equations describing gravitational interaction of the dark ma...

Photometric distances to dark clouds: cometary globule CG 12

A method for determining distances to dark clouds and Bok globules based on broad-band optical and near-infrared photometry is presented. In this method, intrinsic colour indices of stars projected towards the direction of a cloud are computed by dereddening the observed colour indices using various trial values of extinction AV and a standard extinction law. The computed intrinsic colour indic...

The 6 - GHz methanol multibeam maser catalogue II : Galactic longitudes 6 ◦ to 20 ◦

We present the second portion of an unbiased survey of the Galactic plane for 6668MHz methanol masers. This section of the survey spans the longitude range 6◦ to 20◦. We report the detection of 119 maser sources, of which 42 are new discoveries. The masers are tightly constrained to the Galactic plane, with only four outside a latitude range of ±1◦. This longitude region includes the brightest ...
