The GRAVITY Young Stellar Object survey IV. The CO overtone emission in 51 Oph at sub-au scales
GRAVITY Collaboration, M. Koutoulaki, R. Garcia Lopez +69
51 Oph is a Herbig Ae/Be star that exhibits strong near-infrared CO ro-vibrational emission at 2.3 micron, most likely originating in the innermost regions of a circumstellar disc.…
Triaxiality can explain the alleged dark matter deficiency in some dwarf galaxies
J. Sanchez Almeida, M. Filho
Dark Matter (DM) is an ingredient essential to the current cosmological concordance model. It provides the gravitational pull needed for the baryons to form galaxies. Therefore, th…
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…
Local anti-correlation between star-formation rate and gas-phase metallicity in disk galaxies
J. Sanchez Almeida, N. Caon, C. Munoz-Tunon +2
Using a representative sample of 14 star-forming dwarf galaxies in the local Universe, we show the existence of a spaxel-to-spaxel anti-correlation between the index N2 (log([NII]6…
