Topology of the Galaxy Distribution in the Hubble Deep Fields
We have studied topology of the distribution of the high redshift galaxies identified in the Hubble Deep Field (HDF) North and South. The two-dimensional genus is measured from the projected distributions of the HDF galaxies at angular scales from 3.8 to 6.1. We have also divided the samples into three redshift slices with roughly equal number of galaxies using photometric redshifts to see poss...
متن کاملThe ALMA Frontier Fields Survey - I. 1.1 mm continuum detections in Abell 2744, MACS J0416.1-2403 and MACS J1149.5+2223
Context. Dusty star-forming galaxies are among the most prodigious systems at high redshift (z > 1), characterized by high starformation rates and huge dust reservoirs. The bright end of this population has been well characterized in recent years, but considerable uncertainties remain for fainter dusty star-forming galaxies, which are responsible for the bulk of star formation at high redshift ...
متن کاملThe ASTRODEEP Frontier Fields catalogues - I. Multiwavelength photometry of Abell-2744 and MACS-J0416
Context. The Frontier Fields survey is a pioneering observational program aimed at collecting photometric data, both from space (Hubble Space Telescope and Spitzer Space Telescope) and from ground-based facilities (VLT Hawk-I), for six deep fields pointing at clusters of galaxies and six nearby deep parallel fields, in a wide range of passbands. The analysis of these data is a natural outcome o...
متن کاملOptimizing pixfrac in Astrodrizzle: An example from the Hubble Frontier Fields
We present the results of pixfrac tests conducted for the Hubble Frontier Fields and describe the methodology for optimizing this parameter for any given plate scale. These tests are the final step in the drizzling process and they provide the information necessary for reaching the best possible image resolution using the AstroDrizzle task. They are presented as an example for users to follow. ...
متن کاملThe Hubble Deep Fields
■ Abstract The Hubble space telescope observations of the northern Hubble deep field, and more recently its counterpart in the south, provide detections and photometry for stars and field galaxies to the faintest levels currently achievable, reaching magnitudes V ∼ 30. Since 1995, the northern Hubble deep field has been the focus of deep surveys at nearly all wavelengths. These observations hav...
