The detailed study of the different structural components of nearby galaxies can supply vital information about the secular, or internal, evolution of these...
Thick Disks of Edge-on Galaxies Seen through the Spitzer Survey of Stellar Structure in Galaxies (S4G): Lair of Missing Baryons?
Most, if not all, disk galaxies have a thin (classical) disk and a thick disk. In most models thick disks are thought to be a necessary consequence of the disk...
Thick disks of lenticular galaxies. 3D-photometric thin/thick disk decomposition of eight edge-on s0 galaxies
Thick disks are faint and extended stellar components found around several disk galaxies including our Milky Way. The Milky Way thick disk, the only one studied...
Thin discs, thick dwarfs and the effects of stellar feedback
We investigate the role of stellar mass in shaping the intrinsic thickness of galaxy discs by determining the probability distribution of apparent axial ratios...
Thin shell formation in radiative shocks. 1: Supernova remnants in low-density media
This paper explores the onset of thin-shell formation in interstellar shocks associated with supernova explosions. We outline a simple but useful scheme that...
Third-Order Perturbative Approach to Gravitational Instability: Evolution of Isolated Structures and Environmental Effects
In an Omega 0 = 1 universe, within the classical Eulerian theory of gravitational instability, the redshift evolution of a peculiar velocity field in a region...
Three Lyman-α-emitting filaments converging to a massive galaxy group at z = 2.91: discussing the case for cold gas infall
We have discovered a 300 kpc-wide giant Lyman-α (Lyα) nebula centered on the massive galaxy group RO-1001 at z = 2.91 in the Cosmic Evolution Survey field. Keck...
Three supernova shells around a young M33 star cluster
Using a specialized technique sensitive to the presence of expanding ionized gas, we have detected a set of three concentric expanding shells in an H II region...
Three-dimensional decomposition of galaxies with bulge and long bar
Context. Some observations indicate that the Milky Way has two inner components, a bulge and a long bar, which present a misalignment of Δα ≃ 20° that is...
