Edge-on galaxies in the Hubble Ultra Deep Field

Abstract

We studied a sample of 58 edge-on spiral galaxies at redshifts $z\sim 1$ selected in the Hubble Ultra Deep Field. For all galaxies we analyzed the 2D brightness distributions in the $V_{606}$ and $i_{775}$ filters and measured the radial ($h_r$) and vertical ($h_z$) exponential scales of the brightness distribution. We obtained evidence that the relative thickness of the disks of distant galaxies, i.e., the ratio of the vertical scale height and radial scale length ($h_z/h_r$), on average, exceeds the relative thickness of the disks of nearby spiral galaxies. The vertical scale height $h_z$ of the stellar disks of galaxies shows no big changes at $z\le 1$. The possibility of the evolution of the radial scale length $h_r$ for the brightness distribution with redshift is discussed.
