The giant Lyα nebula associated with a z=2.5 radio galaxy
Villar-Martín, M.; Sánchez, S. F.; Peletier, R.;Vernet, J.; De Breuck, C.; Humphrey, A.;di Serego Alighieri, S.; Fosbury, R.; Stern, D.. The giant Lyα nebula associated with a z=2.5 radio galaxy. Astronomische Nachrichten. 2006, Vol. Vol.327, Issue 2/3, p.187-190 , p. -2006.
We present a kinematic and morphological study of the giant Lyα nebula associated with the radio galaxy MRC 2104-242 (z = 2.49) based on integral field spectroscopic VIMOS data from VLT. The galaxy appears to be embedded in a giant (⪆ 120 kpc) gas reservoir that surrounds it completely. The kinematic properties of the nebula suggest that it is a rotating structure, which would imply a lower limit to the dynamical mass of ˜ 3 × 1011 M_ȯ. An alternate scenario is that the gas is infalling. Such a process would be able to initiate and sustain significant central starburst activity, although it is likely to contribute with less than 10% of the total stellar mass of the galaxy.
