The Hamburg/SAO Survey for Emission–Line Galaxies

, 1999
We present first results of the Hamburg/SAO Survey for Emission-Line Galaxies (HSS therein, SAO – Special Astrophysical Observatory, Russia) which is based on the digitized objective-prism photoplates database of the Hamburg Quasar Survey (HQS). The main

An optical and infrared analysis of blue compact dwarf galaxies [PDF]

, 2010
An understanding of Blue Compact Dwarf galaxies (BCDs) and the processes occurring within their chemically un-evolved environments is fundamental in our understanding of the early universe.

Extremely Metal-poor Galaxies in DESI DR1: Connections to Galaxies in the Early Universe

The Astronomical Journal
Extremely metal-poor galaxies (XMPGs), defined as having metallicities below 10% of the solar value, are considered possible local analogs to primordial systems and offer a unique window into early galaxy evolution.

Thermal emission from H II galaxies: discovering the youngest systems [PDF]

, 2007
We studied the radio properties of very young massive regions of star formation in HII galaxies, with the aim of detecting episodes of recent star formation in an early phase of evolution where the first supernovae start to appear. Our sample consists of
