Exploring the Link between Extreme Coronal Line Emitters and Tidal Disruption Events

The Astrophysical Journal
Galaxies with minimal or no activity from their nucleus can still exhibit significant coronal line (CL) emission, often exceeding the strength of typical narrow emission lines. Many of these CLs require ionization potentials of ≥100 eV, implying the need

DESI Spectroscopy of HETDEX Emission-line Candidates. I. Line Discrimination Validation

The Astrophysical Journal
The Hobby–Eberly Dark Energy Experiment (HETDEX) is an untargeted spectroscopic galaxy survey that uses Ly α- emitting galaxies (LAEs) as tracers of 1.9 < z < 3.5 large-scale structure. Most detections consist of a single emission line, whose identity is

Emission-line galaxies at z ∼ 1 from near-IR HST slitless spectroscopy: metallicities, star formation rates, and redshift confirmations from VLT/FORS2 spectroscopy

We follow up emission line galaxies identified through the near-infrared slitless HST/WFC3 WISP survey with VLT/FORS2 optical spectroscopy. Over 4 WISP fields, we targeted 85 of 138 line emission objects at $0.4\lt z\lt 2$ identified in WFC3 spectroscopy.

An optical and infrared analysis of blue compact dwarf galaxies

, 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.

Searching for emission-line galaxies: The UCM survey

, 1993
We are carrying out a long-term project with the main purposes of finding and analyzing low metallicity galaxies. A very small number of very low metallicity galaxies is known up to now.
