The impact of Warm Dark Matter of the ages of galaxies . ... Nicola Menci (INAF-Rome) and collaborators have delevoped a model (the Rome semi-analytic model) that connects the physics of gas and star formation in galaxies with the merging history of dark matter halo in a Warm Dark Matter scenario. ...

... According to the most popular cosmological paradigm, the greater part of the galaxy mass is accumulated in the dark matter halo. ... The polar ring galaxies (PRGs) reveal external rings or disks of gas, dust and stars rotating in a plane roughly perpendicular to the disk of the central galaxy. ... The shape of the dark halo in the model was chosen so as to achieve the best fit to the observed rotation of both galaxies themselves and their polar rings. ... The SPRC-7 galaxy. ...

... Magnetic fields, subatomic particles, etc., traveling in different directions fill the universe. Do they deflect or otherwise affect one another? If so, isnт??t the information we get from them distorted? ... Neutrino astronomy, which is still in its infancy, is attractive because neutrinos interact so weakly with matter that few of these distorting effects occur.

Next: Transparency of the Stochastic Up: Model of the Galaxy Previous: Frequency distribution of galactic . ... The parameters of the model resulted from a numerical fitting of various data, such as the observed distribution of the young star population and neutral hydrogen, the density of population II stars in the vicinity of the Sun, the galactic rotation curve and the dynamics and distribution of globular clusters   and dwarf irregular satellites of the Galaxy. ...

Since the first stars and then galaxies formed the Universe has been an immense factory converting neutral gas into stellar material. ... In this seminar I will discuss recent results from the Galaxy And Mass Assembly (GAMA) survey, probing the assembly of stellar mass though both in-situ star formation (as traced by multiple SFR indicators) and interactions (both mergers and interaction induced star-formation) - in galaxies spanning ~4 decades in stellar mass. ...

The quantity of dust in a spiral disk can be estimated using the dust's typical emission or the extinction of a known source. In this paper we compare two techniques, one based on emission and one on absorption, applied to sections of 14 disk galaxies. ... Hence, they depend differently on the average number and optical depth of ISM structures in the disk. The small-scale geometry of the cold ISM is critical for accurate models of the overall energy budget of spiral disks. ...

In order to investigate the cosmological evolution of star-forming galaxies it is essential that we understand the physics which controls the evolution and regulation of star formation in the ISM. ...
