Context. In the concordance cosmological scenario, the cold collisionless dark matter component dominates the mass budget of galaxies and interacts with baryons only via gravity. However, there is growing evidence that the former, instead, responds to the baryonic (feedback) processes by modifying its density distribution. These processes can be captured by comparing the inner dynamics of galaxies across cosmic time. Aims. We present a pilot study of dynamical mass modeling of high redshift…

Observational constraints on stellar feedback in dwarf galaxies

Feedback to the interstellar medium (ISM) from ionising radiation, stellar winds and supernovae is central to regulating star formation in galaxies. Due to their low mass ( M ∗ < 10 9 M (cid:12) ),

Dehnen halo effect on a black hole in an ultra-faint dwarf galaxy

There had been recent advancement toward the detection of ultra-faint dwarf galaxies, which may serve as a useful laboratory for dark matter exploration since some of them contains almost 99% of pure

Dark Matter Fraction in z~1 Star-Forming Galaxies

Context. The study of dark matter (DM) across cosmic timescales is essential for understanding galaxy formation and evolution. Recent observational studies show that further back in time (z > 0.5),
