Young, blue, and isolated stellar systems in the Virgo Cluster. II. A new class of stellar system

Michael G. Jones, David J. Sand, Michele Bellazzini +21

We discuss five blue stellar systems in the direction of the Virgo cluster, analogous to the enigmatic object SECCO 1 (AGC 226067). These objects were identified based on their opt…

A technique to select the most obscured galaxy nuclei

I. García-Bernete, D. Rigopoulou, S. Aalto +5

Compact obscured nuclei (CONs) are mainly found in local U/LIRGs. In the local Universe, these sources are generally selected through the detection of the HCN-vib (3-2) emission li…

IR characteristic emission and dust properties of star-forming galaxies at 4.5 z 6.2

D. Burgarella, J. Bogdanoska, A. Nanni +31

The luminosity functions at z < 4 - 5 suggest that most galaxies have a relatively low stellar mass (logM_star = 10) and a low dust attenuation (A_FUV = 1.0). The physical properti…
