THE OPACITY OF SPIRAL GALAXY DISKS [PDF]
, 2007 The opacity of foreground spiral disks can be probed from the number of distant galaxies seen through them. To calibrate this number for effects other than the dust extinction, Gonzalez et al. (1998) developed the "Synthetic Field Method". A synthetic field is an extincted Hubble Deep Field added to the science field.

Star clusters in unperturbed spiral galaxies [PDF]
, 2008 Stars do not form in isolation, they form in groups known as star clusters. Star clusters are seen in a wide range of galaxies and environments. Their presence reveals the history of the host galaxy and the processes of its star formation.

, 2008 We present a new set of multi-million particle SPH simulations of the formation of disk dominated galaxies in a cosmological context. Some of these galaxies are higher resolution versions of the models already described in Governato et al (2007). To correctly compare simulations with observations we create artificial images of our simulations and from ...

Disk Galaxies at High Redshift? [PDF]
Proceedings of the International Astronomical Union, 2007 AbstractThe successful implementation of integral field near-infrared spectrographs fed by adaptive optics is providing unprecedented views of gas motions within galaxies at redshifts z = 2 − 3, when the universe was forming stars at its peak rate. A complex picture of galaxy kinematics is emerging, with inflows, rotation within sometimes extended and ...

Chemodynamical modeling of young disk galaxies [PDF]
, 2003 Disk galaxies are very complex systems consisting of several components like the bulge, the disk and the halo. Additionally, substructures like extended HI disks, thin and thick stellar disks are observed.

Kinematic Modeling of Distant Galaxies
Open Astronomy, 2012 Evolution of galaxies is one of the most actual topics in astrophysics. Among the most important factors determining the evolution are two galactic components which are difficult or even impossible to detect optically: the gaseous disks and the dark ...

Early assembly of the most massive galaxies [PDF]
, 2009 The current consensus is that galaxies begin as small density fluctuations in the early Universe and grow by in situ star formation and hierarchical merging(1).

Identifying lopsidedness in spiral galaxies using a deep convolutional neural network
Astronomy & AstrophysicsContext. About 30% of disk galaxies exhibit lopsidedness in their stellar disk. Although such a large-scale asymmetry in the disk can be primarily considered as a long-lived mode (m = 1), the physical origin of the lopsidedness in the disk continues to ...
