We present results on the disk-disk major merger fraction evolution up to z˜1 in SPITZER/IRAC selected samples in the GOODS-S field. We pick as merger remnants sources with high asymmetry (A). We take into account the experimental errors in photometric redshift and index A, that tend to overestimate the merger fraction, by maximum likelihood

Determining the magnetic field of solar spicules is vital for developing adequate models of these plasma jets, which are thought to play a key role in the thermal, dynamic, and magnetic structure of the chromosphere. Here we report on magnetic spicule properties in a very quiet region of the off-limb solar atmosphere, as inferred from new

This review presents a panorama of the research topics that are currently being developed by our strategic research group at the IAC in the field of very low-mass stars, brown dwarfs, extrasolar giant planets and the solar system. Our main goal is to investigate the cosmogony of the least massive stellar and substellar component of the Milky Way

In this paper, we study the possible interactions between radiation and the Linen of Turin. The work is in line with the research focused, by scholars and scientists, on the detection mechanism of the Shroud body image formation. We have analysed the interactions between thermal, UV and particle radiation with the linen fabric. The performed

The Photodetector Array Camera and Spectrometer (PACS) is one of the three science instru-ments for ESA's far infrared and submillimeter observatory Herschel. It employs two Ge:Ga photoconductor arrays (stressed and unstressed) with 16 25 pixels, each, and two filled silicon bolometer arrays with 16 32 and 32 64 pixels, respectively, to perform

We use N-body simulations to study the effects of tides on the kinematical structure of satellite galaxies orbiting a Milky Way-like potential. Our work is motivated by observations of dwarf spheroidal galaxies in the Local Group, for which often a distinction is possible between a cold centrally concentrated metal rich and a hot, extended metal
