Observations of H2O isotopologues of the extreme OH/IR star OH 26.5+0.6 show that the star has an initial mass consistent with it being an intermediate-mass...
Mass Loss in Galactic Globulars: Red Giant Stragglers and Helium White Dwarfs
The evolution of Population II Red Giants has been studied by adopting Reimers' formalism for the efficiency of mass loss. Evolutionary computations for models...
We present evidence that recently identified massive rubidium-rich AGB stars also played an important role as sources of certain long-lived and short-lived...
Massive characterisation of subgiants and red giants with TESS (Kepler and Gaia)
TESS serves as a formidable tool for investigating stellar variability. Nonetheless, the adaptation of methodologies employed in other space missions, such as...
Massive compact galaxies in the local Universe: what are they?
Recent investigations have provided evidences that many massive (M_* > 10^{11} M_&sun;) spheroid galaxies in the early universe (z ≥ 1.5) were extremely compact...
Massive galaxies in Extended Groth Strip (Trujillo+, 2007)
We use the Palomar Observatory Wide-field Infrared (POWIR)/DEEP-2 survey (Davis et al., 2003, SPIE, Vol. 4834, p. 161; Bundy et al., 2006ApJ...651..120B...

Massive galaxies: a gate to large area very deep galaxy surveys
Massive (M_{stellar}≥10^{11} h_{70}^{-2} {M}_{&sun;}) galaxies are privileged probes to explore galaxy evolution, as their high luminosities allow us to track...
