Discovery of faint double-peak Halpha emission in the halo of low redshift galaxies
J. Sanchez Almeida, J. Calhau, C. Munoz-Tunon +2
Aiming at the detection of cosmological gas being accreted onto galaxies of the local Universe, we examined the Halpha emission in the halo of 164 galaxies in the field of view of…
Probing the existence of a rich galaxy overdensity at z=5.2
R. Calvi, H. Dannerbauer, P. Arrabal Haro +4
We report the results of a pilot spectroscopic program of a region at z=5.2 in the GOODS-N field containing an overdensity of galaxies around the well-known submillimeter galaxy HD…
Differences and similarities of stellar populations in LAEs and LBGs at 3.4 - 6.8
P. Arrabal Haro, J. M. Rodríguez Espinosa, C. Muñoz-Tuñón +6
The differences between the inherent stellar populations (SPs) of LAEs and LBGs are a key factor in understanding early galaxy formation and evolution. We have run a set of SP burs…
Global Correlations Between the Radio Continuum, Infrared and CO Emission in Dwarf Galaxies
Mercedes E. Filho, Fatemeh S. Tabatabaei, Jorge Sanchez Almeida +2
Correlations between the radio continuum, infrared and CO emission are known to exist for several types of galaxies and across several orders of magnitude. However, the low-mass, l…
A headless tadpole galaxy: the high gas-phase metallicity of the ultra-diffuse galaxy UGC 2162
J. Sanchez Almeida, A. Olmo-Garcia, B. G. Elmegreen +5
The cosmological numerical simulations tell us that accretion of external metal-poor gas drives star-formation (SF) in galaxy disks. One the best pieces of observational evidence s…
NOEMA Observations of a Molecular Cloud in the low-metallicity Galaxy Kiso 5639
Bruce G. Elmegreen, Cinthya Herrera, Monica Rubio +4
A giant star-forming region in a metal-poor dwarf galaxy has been observed in optical lines with the 10-m Gran Telescopio Canarias and in the emission line of CO(1-0) with the NOEM…
