Extremely Metal-Poor Galaxies: The HI Content
M. E. Filho, B. Winkel, Sánchez Almeida +12
Extremely metal-poor (XMP) galaxies are chemically, and possibly dynamically, primordial objects in the local Universe. Our objective is to characterize the HI content of the XMP g…
A Virtual Observatory Census to Address Dwarfs Origins. AVOCADO - I. Science goals, sample selection and analysis tools
R. Sánchez-Janssen, R. Amorín, M. García-Vargas +9
(Abridged) AVOCADO aims at establishing firm conclusions on the formation and evolution of dwarf galaxies by constructing and analysing a homogeneous, multiwavelength dataset for a…
Complex gas kinematics in compact, rapidly assembling star-forming galaxies
Ricardo Amorín, José M. Vílchez, Guillermo Hägele +3
Deep, high resolution spectroscopic observations have been obtained for six compact, strongly star-forming galaxies at redshift z~0.1-0.3, most of them also known as Green Peas. Re…
The star formation history and metal content of the "Green Peas". New detailed GTC-OSIRIS spectrophotometry of three galaxies
Ricardo Amorín, E. Pérez-Montero, J. M. Vílchez +1
We present deep broad-band imaging and long-slit spectroscopy of three compact, low-mass starburst galaxies at redshift z\sim0.2-0.3, also referred to as Green Peas (GP). We measur…
On the oxygen and nitrogen chemical abundances and the evolution of the "green pea" galaxies
Ricardo O. Amorín, E. Pérez-Montero, J. M. Vílchez
We have investigated the oxygen and nitrogen chemical abundances in extremely compact star-forming galaxies with redshifts between 0.11-0.35, popularly referred to as "green…
Search for blue compact dwarf galaxies during quiescence II: metallicities of gas and stars, ages, and star-formation rates
J. Sanchez Almeida, J. A. L. Aguerri, C. Munoz-Tunon +1
We examine the metallicity and age of a large set of SDSS/DR6 galaxies that may be Blue Compact Dwarf (BCD) galaxies during quiescence (QBCDs).The individual spectra are first clas…
