Kant and extragalactic revolution in astronomy

Theoria, Beograd, 2004
In this paper we briefly consider the role Kant's early philosophy, and notably his "island universes" hypothesis played in the history of astronomy. There are many reasons for this, including the coincidence of Kant's jubilee year with 80 years since Hubble's discovery (1924) of the extragalactic universe.

Are Radio Minihalos Confined by Cold Fronts in Galaxy Clusters? Minihalos and Large-scale Sloshing in A3444 and MS 1455.0+2232

The Astrophysical Journal
We present radio and X-ray studies of A3444 and MS1455.0+2232, two galaxy clusters with radio minihalos in their cool cores. A3444 is imaged using the Giant Metrewave Radio Telescope (GMRT) at 333, 607, and 1300 MHz and the Very Large Array at 1435 MHz ...

Extragalactic Astronomy: From Pioneers to Big Science

, 2016
At the beginning of the XIX century one of the scientific issues driving the research of astronomers, like the Herschels, was to test if all the nebulæ can be resolved into stars. This research continued uninterruptedly for many years surveying the nebulæ in the Charles Messier’s “Catalogue des n´ebuleuse et des amas d’´etoiles” published in 1780 and ...

CHILES. IX. Observational and Simulated H i Content and Star Formation of Blue Galaxies in Different Cosmic Web Environments

The Astrophysical Journal
We examine the redshift evolution of the relationship between the neutral atomic hydrogen (H i ) content and star formation properties of blue galaxies, along with their location in the cosmic web. Using the COSMOS H i Large Extragalactic Survey (CHILES)
