Evolution of the Fundamental Plane for early-type galaxies up to z = 1.2

We studied the evolution of the Fundamental Plane in B- and g-bands, for
two samples of early-type galaxies at 0.2 < z < 0.35 and 0.35 <
z < 1.2. We found a difference in the intercept that can be
interpreted as galaxies at < z > ~0.7 being 0.68 and 0.52 mag
brighter in the B- and g-band respectively, than their local
counterparts. From the study of the Kormendy relation, we found the
existence of a population of very bright (-21.5 > M <SUB>g</SUB> >
-22.5) and compact (Re < 2 kpc) galaxies of which only a small
fraction of 0.4% exists at z =…

The UV to FIR spectral energy distribution of star-forming galaxies in the redshift desert

We analyze the rest-frame UV-to-near-IR spectral energy distribution
(SED) of Lyman break galaxies (LBGs), star-forming (SF) BzK (sBzK), and
UV-selected galaxies at 1.5 < z < 2.5 in the COSMOS, GOODS-North,
and GOODS-South fields. Additionally, we complement the multi-wavelength
coverage of the galaxies located in GOODS-North and GOODS-South fields
with deep FIR data taken within the framework of the GOODS-Herschel
project. According to their best-fitted SED-derived properties we find
that, due to their selection criterion involving UV measurements, LBGs
tend to be UV-brighter,…


Lyman break and ultraviolet-selected galaxies at z ˜ 1 - I. Stellar populations from the ALHAMBRA survey

We take advantage of the exceptional photometric coverage provided by
the combination of GALEX data in the ultraviolet (UV) and the ALHAMBRA
survey in the optical and near-infrared to analyse the physical
properties of a sample of 1225 GALEX-selected Lyman break galaxies
(LBGs) at 0.8 ≲ z ≲ 1.2 that are located in the COSMOS field.
This is the largest sample of LBGs studied in this redshift range to
date. According to a spectral energy distribution (SED) fitting with
synthetic stellar population templates, we find that LBGs at z ˜ 1
are mostly young galaxies with a median age of 341 Myr and…


A real-time data acquisition and elaboration system for instabilities control in the FTU tokamak

A real-time data acquisition and elaboration system is being implemented
to control the new ECH launcher recently installed at FTU (Frascati
Tokamak Upgrade). The system is aimed at controlling different kinds of
magnetohydrodynamic instabilities, in particular the deleterious 3/2 and
2/1 (neoclassical) tearing modes, (N)TM, and the saw teeth period in
order to prevent the seeding of NTMs. The complete system is presented
here together with preliminary offline and real-time tests. © 2001
