The Influential Roles of Gravity, Turbulence, and Magnetic Fields in Shaping the Physical Evolution of Dense Massive Clumps
Moses Onyemaechi Asogwa, Seblu Humne Negu, Gemechu Muleta Kumssa +1
We explore the roles of the three competitors, namely, gravity, turbulence, and magnetic fields, in controlling star formation (SF) within dense, massive clumps identified in the A…

The miniJPAS survey: AGN & host galaxy co-evolution of X-ray selected sources
I. E. López, M. Brusa, S. Bonoli +35
Studies indicate strong evidence of a scaling relation in the local Universe between the supermassive black hole mass ($M_\rm{BH}$) and the stellar mass of their host galaxies ($M_…
The Lockman-SpReSO project. Description, target selection, observations and preliminary results
M. González-Otero, C. P. Padilla-Torres, J. Cepa +26
Context. Extragalactic surveys are a key tool for better understanding the evolution of galaxies. Both deep and wide-field surveys serve to provide a clearer emerging picture of th…
The miniJPAS Survey: Detection of double-core Lyα morphology of two high-redshift (z>3) QSOs
P. T. Rahna, Zhen-Ya Zheng, Ana L. Chies-Santos +30
The Ly emission is an important tracer of neutral gas in a circum-galactic medium (CGM) around high-z QSOs. The origin of Lya emission around QSOs is still under debate which ha…
Stellar populations of a sample of far-IR AGN and non-AGN green valley galaxies
Antoine Mahoro, Mirjana Pović, Petri Väisänen +2
We present a study on the stellar populations and stellar ages of sub-sample of far-infrared AGN and non-AGN green valley analysed in Mahoro et al. (2017,2019) at 0.6 < z < 1.0 usi…
Effect of AGN on the morphological properties of their host galaxies in the local Universe
T. Getachew-Woreta, M. Povic, J. Masegosa +3
The morphological classification of active galaxies may be affected by the presence of active galactic nuclei (AGN). In this paper, we provide the most detailed analysis on how dif…
The OTELO survey as a morphological probe. Last ten Gyr of galaxy evolution. The mass--size relation up to z=2
Jakub Nadolny, Ángel Bongiovanni, Jordi Cepa +14
The morphology of galaxies provide us with a unique tool for relating and understanding other physical properties and their changes over the course of cosmic time. It is only recen…
Kinematics and Multi Band Period-Luminosity-Metallicity Relation of RR Lyrae Stars via Statistical Parallax
T. D. Muhie, A. K. Dambis, L. N. Berdnikov +2
This paper presents results from photometric and statistical-parallax analysis of a sample of 850 field RR Lyrae (RRL) variables. The photometric and spectroscopic data for sample…
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…
AGN and Star-Formation Properties of Inside-out Assembled Galaxy Candidates at z<0.1
Dejene Zewdie, Mirjana Pović, Manuel Aravena +2
We study a sample of 48127 galaxies selected from the SDSS MPA-JHU catalogue, with and . Local galaxies in this stellar mass range…
Galaxy classification: deep learning on the OTELO and COSMOS databases
José A. de Diego, Jakub Nadolny, Ángel Bongiovanni +19
Context. The accurate classification of hundreds of thousands of galaxies observed in modern deep surveys is imperative if we want to understand the universe and its evolution. Aim…

Mirjana Pović
In this paper we summarise the research that is currently going on in Ethiopia and East-Africa in extragalactic astronomy and physics of active galaxies and active galactic nuclei…
Study of AGN contribution on morphological parameters of their host galaxies
Tilahun Getachew-Woreta, Mirjana Pović, Josefa Masegosa +3
We tested how the AGN contribution (5% - 75% of the total flux) may affect different morphological parameters commonly used in galaxy classification. We carried out all analysis at…
