Higgs-portal dark matter from non-supersymmetric strings
Esau Cervantes, Omar Perez-Figueroa, Ricardo Perez-Martinez +1
Large classes of non-supersymmetric string models equipped with standard-model features have been constructed, but very little of their phenomenology is known. Interestingly, their…
Galaxy And Mass Assembly (GAMA): The environmental impact on SFR and metallicity in galaxy groups
D. Sotillo-Ramos, M. A. Lara-Lopez, A. M. Perez-Garcia +7
We present a study of the relationships and environmental dependencies between stellar mass, star formation rate, and gas metallicity for more than 700 galaxies in groups up to red…
The OTELO survey: the star formation rate evolution of low-mass galaxies
Bernabé Cedrés, Ana María Pérez-García, Ricardo Pérez-Martínez +14
We present the analysis of a sample of \ha\,, \hb\ and \oii\ emission line galaxies from the \otelo\ survey, with masses typically below $log(M_*/M_\sun) \sim 9.4$ and redshifts be…
The landscape of promising non-supersymmetric string models
Ricardo Perez-Martinez, Saul Ramos-Sanchez, Patrick K. S. Vaudrevange
Leptoquarks extending the Standard Model (SM) are attracting an increasing attention in the recent literature. Hence, the identification of 4D SM-like models and the classification…
GLACE survey: galaxy activity in ZwCl0024+1652 cluster from strong optical emission lines
Zeleke Beyoro-Amado, Miguel Sánchez-Portal, Angel Bongiovanni +9
Although ZwCl0024+1652 galaxy cluster at has been thoroughly analysed, it lacks a comprehensive study of star formation and nuclear activity of its members. With GaLAxy…
U(1)' coupling constant at low energies from heterotic orbifolds
Yessenia Olguin-Trejo, Omar Perez-Figueroa, Ricardo Perez-Martinez +1
Additional Abelian gauge interactions are generic to string compactifications. In heterotic string models, gauge coupling unification of such forces and other gauge interactions is…
