EMIR confirmation of the high-z Lyα blob SHARDS20018464
S. Zarattini, F. Garzón, C. Muñoz-Tuñón
A spectroscopic follow-up of the Ly blob SHARDS20018464 was performed using the infrared spectrograph EMIR (Espectrógrafo Multiobjeto Infra-Rojo) at the 10.4 m GTC telescope, eq…
Local and global gas metallicity versus stellar age relation in MaNGA galaxies
Laura Sánchez-Menguiano, Jorge Sánchez Almeida, Casiana Muñoz-Tuñón +1
The search for new global scaling relations linking physical properties of galaxies has a fundamental interest. Furthermore, their recovery from spatially resolved relations has be…
On the star formation efficiencies and evolution of multiple stellar generations in Globular Clusters
Guillermo Tenorio-Tagle, Sergiy Silich, Jan Palous +2
By adopting empirical estimates of the Helium enhancement (Delta Y) between consecutive stellar generations for a sample of Galactic globular clusters (GGC), we uniquely constraint…
The stellar host in star-forming low-mass galaxies: Evidence for two classes
A. Lumbreras-Calle, J. Méndez-Abreu, C. Muñoz-Tuñón
The morphological evolution of star-forming galaxies provides important clues to understand their physical properties, as well as the triggering and quenching mechanisms of star fo…
Characterizing the local relation between star formation rate and gas-phase metallicity in MaNGA spiral galaxies
Laura Sánchez-Menguiano, Jorge Sánchez Almeida, Casiana Muñoz-Tuñón +4
The role of gas accretion in galaxy evolution is still a matter of debate. The presence of inflows of metal-poor gas that trigger star formation bursts of low metallicity has been…
Pyroclastic Blowout: Dust Survival in Isolated versus Clustered Supernovae
Sergio Martínez-González, Richard Wünsch, Jan Palouš +3
Following the current debate on the fate of SN-condensed dust grains, here we explore by means of three-dimensional hydrodynamical simulations the interaction of dusty supernova re…
A simultaneous search for High- LAEs and LBGs in the SHARDS survey
P. Arrabal Haro, J. M. Rodríguez Espinosa, C. Muñoz-Tuñón +15
We have undertaken a comprehensive search for both Lyman Alpha Emitters (LAEs) and Lyman Break Galaxies (LBGs) in the SHARDS Survey of the GOODS-N field. SHARDS is a deep imaging s…
Star-forming galaxies at low-redshift in the SHARDS survey
A. Lumbreras-Calle, C. Muñoz-Tuñón, J. Méndez-Abreu +13
The physical processes driving the evolution of star formation (SF) in galaxies over cosmic time still present many open questions. Recent galaxy surveys allow now to study these p…
The Kennicutt-Schmidt Relation in Extremely Metal-Poor Dwarf Galaxies
M. E. Filho, J. Sánchez Almeida, R. Amorín +3
The Kennicutt-Schmidt (KS) relation between the gas mass and star formation rate (SFR) describes the star formation regulation in disk galaxies. It is a function of gas metallicity…
Search for Extremely Metal-poor Galaxies in the Sloan Digital Sky Survey (II): high electron temperature objects
J. Sanchez Almeida, E. Perez-Montero, A. B. Morales-Luis +4
Extremely metal-poor (XMP) galaxies are defined to have gas-phase metallicity smaller than a tenth of the solar value (12 + log[O/H] < 7.69). They are uncommon, chemically and poss…
Molecular gas in low-metallicity starburst galaxies: Scaling relations and the CO-to-H conversion factor
Ricardo Amorín, C. Muñoz-Tuñón, J. A. L. Aguerri +1
We study the molecular content and the star formation efficiency of 21 Blue Compact Dwarfs (BCDs). We present CO(1-0) and (2-1) observations, further supplemented with additional C…
On the use of the index N2 to derive the metallicity in metal-poor galaxie
A. B. Morales-Luis, E. Perez-Montero, J. Sanchez Almeida +1
The N2 index ([N II]6584/Ha) is used to determine emission line galaxy metallicities at all redshifts, including high redshift, where galaxies tend to be metal-poor. The initial ai…
Interacting LAEs at z = 5.1. Episodic star formation in a group of LAEs at z= 5.07
J. M. Rodriguez Espinosa, O. Gonzalez-Martin, N. Castro Rodriguez +9
We are undertaking a search for high-redshift low luminosity Lyman Alpha sources in the SHARDS survey. Among the pre-selected Lyman Alpha sources 2 candidates were spotted, located…
Dusty supernovae running the thermodynamics of the matter reinserted within young and massive super stellar clusters
Guillermo Tenorio-Tagle, Sergiy Silich, Sergio Martínez-González +3
Following the observational and theoretical evidence that points at core collapse supernovae as major producers of dust, here we calculate the hydrodynamics of the matter reinserte…
Massive Clumps in Local Galaxies: Comparisons with High-Redshift Clumps
Bruce G. Elmegreen, Debra Meloy Elmegreen, Jorge Sanchez Almeida +5
Local UV-bright galaxies in the Kiso survey include clumpy systems with kpc-size star complexes that resemble clumpy young galaxies in surveys at high redshift. We compare clump ma…
