We present a detailed comparison of two approaches, the use of a precalculated database and simulated annealing (SA), for fitting the continuum spectral energy distribution (SED) of astrophysical objects whose app...

Embedded clusters are ideal laboratories for understanding the early phase of the dynamical evolution of clusters as well as massive star formation. An interesting observational phenomenon is that some of the embedded...

For the first time, the OMC-2/3 region was mapped in C2H (1–0), HC3N (10–9) and HNC (1–0) lines. In general, the emissions from all the three molecular species reveal an extended filamentary structure. The di...
