The tidal evolution of the Fornax dwarf spheroidal and its globular clusters (2021)
Journal Article
Borukhovetskaya, A., Errani, R., Navarro, J. F., Fattahi, A., & Santos-Santos, I. (2022). The tidal evolution of the Fornax dwarf spheroidal and its globular clusters. Monthly Notices of the Royal Astronomical Society, 509(4), 5330-5339. https://doi.org/10.1093/mnras/stab2912

The dark matter content of the Fornax dwarf spheroidal galaxy inferred from its kinematics is substantially lower than expected from LCDM cosmological simulations. We use N-body simulations to examine whether this may be the result of Galactic tides.... Read More about The tidal evolution of the Fornax dwarf spheroidal and its globular clusters.

Magellanic satellites in ΛCDM cosmological hydrodynamical simulations of the Local Group (2021)
Journal Article
Santos-Santos, I. M., Fattahi, A., Sales, L. V., & Navarro, J. F. (2021). Magellanic satellites in ΛCDM cosmological hydrodynamical simulations of the Local Group. Monthly Notices of the Royal Astronomical Society, 504(3), 4551-4567. https://doi.org/10.1093/mnras/stab1020

We use the APOSTLE ΛCDM cosmological hydrodynamical simulations of the Local Group to study the recent accretion of massive satellites into the halo of Milky Way (MW)-sized galaxies. These systems are selected to be close analogues to the Large Magel... Read More about Magellanic satellites in ΛCDM cosmological hydrodynamical simulations of the Local Group.

Velocity-dependent J-factors for annihilation radiation from cosmological simulations (2021)
Journal Article
Board, E., Bozorgnia, N., Strigari, L. E., Grand, R. J., Fattahi, A., Frenk, C. S., Marinacci, F., Navarro, J. F., & Oman, K. A. (2021). Velocity-dependent J-factors for annihilation radiation from cosmological simulations. Journal of Cosmology and Astroparticle Physics, 2021(04), Article 070. https://doi.org/10.1088/1475-7516/2021/04/070

We determine the dark matter pair-wise relative velocity distribution in a set of Milky Way-like halos in the Auriga and APOSTLE simulations. Focusing on the smooth halo component, the relative velocity distribution is well-described by a Maxwell-Bol...

Observing the Stellar Halo of Andromeda in Cosmological Simulations: The AURIGA2PANDAS Pipeline (2021)
Journal Article
Thomas, G. F., Martin, N. F., Fattahi, A., Ibata, R. A., Helly, J., McConnachie, A. W., Frenk, C., Gómez, F. A., Grand, R. J., Gwyn, S., Mackey, D., Marinacci, F., & Pakmor, R. (2021). Observing the Stellar Halo of Andromeda in Cosmological Simulations: The AURIGA2PANDAS Pipeline. Astrophysical Journal, 910(2), Article 92. https://doi.org/10.3847/1538-4357/abdfd2

We present a direct comparison of the Pan-Andromeda Archaeological Survey (PAndAS) observations of the stellar halo of M31 with the stellar halos of six galaxies from the Auriga simulations. We process the simulated halos through the Auriga2PAndAS pi... Read More about Observing the Stellar Halo of Andromeda in Cosmological Simulations: The AURIGA2PANDAS Pipeline.
