Searching for intergalactic star forming regions in Stephan's Quintet with SITELLE: II. Physical properties and metallicity
S. Duarte Puertas, J. M. Vilchez, J. Iglesias-Páramo +5
Based on SITELLE spectroscopy, we studied the ionised gas emission for the 175 H emission regions in the Stephan's Quintet (SQ). A detailed analysis is performed of the star for…
Mapping the ionized gas of the metal-poor HII galaxy PHL 293B with MEGARA
C. Kehrig, J. Iglesias-Paramo, J. M. Vilchez +14
Here we report the first spatially resolved spectroscopic study for the galaxy PHL293B using the high-resolution GTC/MEGARA IFU. PHL293B is a local, extremely metal-poor, high ioni…
Photon leaking or very hard ionizing radiation? Unveiling the nature of heII-emitters using the softness diagram
E. Pérez-Montero, C. Kehrig, J. M. Vílchez +3
Star-forming galaxies with nebular HeII emission contain very energetic ionizing sources of radiation, which can be considered as analogs to the major contributors of the reionizat…
Properties of five z~0.3-0.4 confirmed LyC leakers: VLT/XShooter observations
N. G. Guseva, Y. I. Izotov, D. Schaerer +7
Using new VLT/XShooter spectral observations we analyse the physical properties of five z~0.3-0.4 confirmed LyC leakers. Strong resonant MgII 2796,2803 emission lines (I(2796,2803)…
The miniJPAS survey: a preview of the Universe in 56 colours
S. Bonoli, A. Marín-Franch, J. Varela +166
The Javalambre-Physics of the Accelerating Universe Astrophysical Survey (J-PAS) will soon start to scan thousands of square degrees of the northern extragalactic sky with a unique…
