The inclination of the dwarf irregular galaxy Holmberg II
, 2014 We provide constraints on the inclination angle of the H\,{\sc i} disk of the dwarf irregular galaxy Holmberg II (Ho II) from stability analysis of the outer gaseous disk. We point out that a mean inclination angle of 27 degrees and thus a flat circular velocity of ~60 km/s, is required to have a level of gravitational stability similar to that found ...

Confronting fuzzy dark matter with the rotation curves of nearby dwarf irregular galaxies [PDF]
Astronomy & Astrophysics, 2023 We investigate phenomenologically the viability of fuzzy dark matter (FDM). We do this by confronting the predictions of the model, in particular, the formation of a solitonic core at the center of dark matter halos, with a homogeneous and robust sample ...

Determining the Timescale over Which Stellar Feedback Drives Turbulence in the Interstellar Medium: A Study of Four Nearby Dwarf Irregular Galaxies [PDF]
Astronomical Journal, 2022 Stellar feedback is fundamental to the modeling of galaxy evolution, as it drives turbulence and outflows in galaxies. Understanding the timescales involved are critical for constraining the impact of stellar feedback on the interstellar medium.

Dark Matter search in dwarf irregular galaxies with the Fermi Large Area Telescope [PDF]
International Conference on Rebooting Computing, 2021 We analyze 11 years of Fermi-LAT data corresponding to the sky regions of 7 dwarf irregular (dIrr) galaxies. DIrrs are dark matter (DM) dominated systems, proposed as interesting targets for the indirect search of DM with gamma rays.

A Search for Correlations between Turbulence and Star Formation in LITTLE THINGS Dwarf Irregular Galaxies [PDF]
, 2021 Turbulence has the potential for creating gas density enhancements that initiate cloud and star formation (SF), and it can be generated locally by SF. To study the connection between turbulence and SF, we looked for relationships between SF traced by FUV

Physical parameters of red supergiants in dwarf irregular galaxies in the Local Group [PDF]
Astronomy & Astrophysics, 2019 Context. Increasing the statistics of evolved massive stars in the Local Group enables investigating their evolution at different metallicities. During the late stages of stellar evolution, the physics of some phenomena, such as episodic and systematic ...

Commodity risk assessment of Quercus robur plants from the UK
EFSA Journal, Volume 21, Issue 10, October 2023., 2023 Abstract The European Commission requested the EFSA Panel on Plant Health to prepare and deliver risk assessments for commodities listed in Commission Implementing Regulation (EU) 2018/2019 as ‘High‐risk plants, plant products and other objects’. This Scientific Opinion covers plant health risks posed by plants of Quercus robur imported from the UK as:
