New clues on the extended HeII ionization in IZw18 from GTC/MEGARA and JWST/MIRI
A. Arroyo-Polonio, C. Kehrig, J. M. Vílchez +5
IZw18 is one of the lowest-metallicity star-forming galaxies known at z0, considered a unique local analogue of the first galaxies. The origin of its hard ionizing continuum,…
A new Einstein Cross gravitational lens of a Lyman-break galaxy
D. Bettoni, R. Falomo, R. Scarpa +5
We report the study of an "Einstein Cross" configuration first identified in a set of HST images by Cerny et al. 2018. Deep spectroscopic observations obtained at the Spanish 10.4m…
Spatially resolved spectroscopy and chemical history of star-forming galaxies in the Hercules cluster: the effects of the environment
V. Petropoulou, J. M. Vílchez, J. Iglesias-Páramo +4
Spatially resolved spectroscopy has been obtained for a sample of 27 star-forming (SF) galaxies selected from our deep Halpha survey of the Hercules cluster. We have applied spectr…
Star forming galaxies in the Hercules cluster: Halpha imaging of A2151
B. Cedres, J. Iglesias-Paramo, J. M. Vilchez +3
This paper presents the first results of an Halpha imaging survey of galaxies in the central regions of the A2151 cluster. A total of 50 sources were detected in Halpha. The morpho…
Recent star formation in clusters of galaxies: extreme compact starbursts in A539 and A634
D. Reverte, J. M. Vílchez, J. D. Hernández-Fernández +1
We report on the detection of two Halpha-emitting extreme compact objects from deep images of the Abell 634 and Abell 539 clusters of galaxies at z ~ 0.03. Follow up long slit spec…
The short-duration GRB 050724 host galaxy in the context of the long-duration GRB hosts
J. Gorosabel, A. J. Castro-Tirado, S. Guziy +11
We report optical and near-infrared broad band observations of the short-duration GRB 050724 host galaxy, used to construct its spectral energy distribution (SED). Unlike the hosts…
