Search for annihilating Dark Matter towards dwarf galaxies with the Cherenkov Telescope Array
EPJ Web of Conferences, 2017 The standard model of cosmology indicates that approximately 27% of the energy density of the Universe is in the form of dark matter. The nature of dark matter is an open question in modern physics.

WFPC2 Observations of the Carina Dwarf Spheroidal Galaxy.
The Astronomical Journal, 1997 We present our analysis of Hubble Space Telescope Wide Field Planetary Camera 2 observations in F555W (~V) and F814W (~I) of the Carina dwarf spheroidal galaxy. The resulting V vs (V-I) color-magnitude diagrams reach V ~ 27.1 mag. The reddening of Carina is estimated to be E(V-I) = 0.08 +- 0.02 mag.

The Binary Fraction of Stars in the Dwarf Galaxy Ursa Minor via Dark Energy Spectroscopic Instrument
The Astrophysical JournalWe utilize multiepoch line-of-sight velocity measurements from the Milky Way Survey of the Dark Energy Spectroscopic Instrument to estimate the binary fraction for member stars in the dwarf spheroidal galaxy Ursa Minor (UMi).

Mass Modelling of dwarf Spheroidal Galaxies [PDF]
, 2017 We study the origin and properties of unbound stars in the kinematic samples of dwarf spheroidal galaxies. For this purpose we have run a high resolution N-body simulation of a two-component dwarf galaxy orbiting in a Milky Way potential.

Measuring the star formation rate density from CNOC2 [PDF]
, 2006 This thesis charts the evolution of the Universal Star Formation Rate Density (SFRD) across the redshift range 0.2 < z < 0.6, using the 2nd Canadian Network for Observational Cosmology Survey (CN0C2).

Fuzzy Dark Matter and the Impact of Core–Halo Diversity on Its Particle Mass Constraints
The Astrophysical JournalWe investigate how diversity in the core–halo mass relation and the inclusion of higher-order velocity moments affect constraints on the fuzzy dark matter particle mass ( m _ψ ) inferred from the internal kinematics of dwarf galaxies.
