Detection and characterization of detached tidal dwarf galaxies

Javier Zaragoza-Cardiel, Beverly J. Smith, Mark G. Jones +7

Tidal interactions between galaxies often give rise to tidal tails, which can harbor concentrations of stars and interstellar gas resembling dwarf galaxies. Some of these tidal dwa…

Mapping the Hubble Flow from z0 to z7.5 with HII Galaxies

Ricardo Chávez, Roberto Terlevich, Elena Terlevich +7

Over twenty years ago, Type Ia Supernovae (SNIa) observations revealed an accelerating Universe expansion, suggesting a significant dark energy presence, often modelled as a cosmol…

A luminous and young galaxy at z=12.33 revealed by a JWST/MIRI detection of Hα and [OIII]

Jorge A. Zavala, Marco Castellano, Hollis B. Akins +37

The James Webb Space Telescope (JWST) has discovered a surprising population of bright galaxies in the very early universe (<500 Myrs after the Big Bang) that is hard to explain wi…

Determination of the local Hubble constant using Giant extragalactic HII regions and HII galaxies

David Fernández-Arenas, Ricardo Chávez

The relationship between the integrated H line luminosity and the velocity dispersion of the ionized gas of HII galaxies and giant HII regions represents an exciting standard ca…

The stellar population responsible for a kiloparsec size superbubble seen in the JWST "phantom" images of NGC628

Y. D. Mayya, J. A. Alzate, L. Lomelí-Núñez +11

We here study the multi-band properties of a kiloparsec-size superbubble in the late-type spiral galaxy NGC628. The superbubble is the largest of many holes seen in the early relea…

The L - σ relation for HII galaxies in green

Jorge Melnick, Eduardo Telles, Vinicius Bordalo +7

The correlation between emission-line luminosity (L) and profile width (sigma) for HII Galaxies provides a powerful method to measure the distances to galaxies over a wide range of…
