The NIVARIA-Local Group simulations: Unveiling the origin of rotation curve diversity in dwarf galaxies and its connection to galaxy morphology
A. Contreras-Santos, A. Di Cintio, A. Negri +7
Dwarf galaxies exhibit a large diversity in rotation curve shapes, challenging galaxy formation models within the CDM paradigm. We present NIVARIA-LG, a new suite of cosmologica…
The undiscovered ultra-diffuse galaxies of the Local Group
Oliver Newton, Arianna Di Cintio, Salvador Cardona-Barrero +6
Ultra-diffuse galaxies (UDGs) are attractive candidates to probe cosmological models and test theories of galaxy formation at low masses; however, they are difficult to detect beca…
A probabilistic deep learning model to distinguish cusps and cores in dwarf galaxies
J. Expósito-Márquez, C. B. Brook, M. Huertas-Company +4
Numerical simulations within a cold dark matter (DM) cosmology form halos whose density profiles have a steep inner slope (`cusp'), yet observations of galaxies often point towards…
Metallicity profiles of Ultra Diffuse Galaxies in NIHAO simulations
S. Cardona-Barrero, A. Di Cintio, G. Battaglia +2
Supernovae feedback driven expansion has proven to be a viable mechanism to explain the average properties of Ultra Diffuse Galaxies (UDGs) such as the sizes, colors, mass and inte…
A rumble in the dark: signatures of self-interacting dark matter in Super-Massive Black Hole dynamics and galaxy density profiles
Arianna Di Cintio, Michael Tremmel, Fabio Governato +5
We explore for the first time the effect of self-interacting dark matter (SIDM) on the dark matter (DM) and baryonic distribution in massive galaxies formed in hydrodynamical cosmo…
NIHAO XI: Formation of Ultra-Diffuse Galaxies by outflows
Arianna Di Cintio, Chris B. Brook, Aaron A. Dutton +3
We address the origin of Ultra-Diffuse Galaxies (UDGs), which have stellar masses typical of dwarf galaxies but effective radii of Milky Way-sized objects. Their formation mechanis…
Testing Feedback-Modified Dark Matter Haloes with Galaxy Rotation Curves: Estimation of Halo Parameters and Consistency with CDM
Harley Katz, Federico Lelli, Stacy S. McGaugh +3
Cosmological -body simulations predict dark matter (DM) haloes with steep central cusps (e.g. NFW, Navarro et al. 1996). This contradicts observations of gas kinematics in low-m…
NIHAO IX: the role of gas inflows and outflows in driving the contraction and expansion of cold dark matter haloes
Aaron A. Dutton, Andrea V. Macciò, Avishai Dekel +7
We use ~100 cosmological galaxy formation zoom-in simulations using the smoothed particle hydrodynamics code {\sc gasoline} to study the effect of baryonic processes on the mass pr…
The mass discrepancy acceleration relation in a CDM context
Arianna Di Cintio, Federico Lelli
The mass discrepancy acceleration relation (MDAR) describes the coupling between baryons and dark matter (DM) in galaxies: the ratio of total-to-baryonic mass at a given radius ant…
The distribution of mass components in simulated disc galaxies
Isabel M. Santos-Santos, Chris B. Brook, Greg Stinson +5
Using 22 hydrodynamical simulated galaxies in a LCDM cosmological context we recover not only the observed baryonic Tully-Fisher relation, but also the observed "mass discrepancy--…
Signatures of Dark Matter Halo Expansion in Galaxy Populations
Chris B. Brook, Arianna Di Cintio
Dark matter cores within galaxy haloes can be formed by energy feedback from star forming regions: an energy balance suggests that the maximum core formation efficiency arises in g…
NIHAO IV: Core creation and destruction in dark matter density profiles across cosmic time
Edouard Tollet, Andrea V. Macciò, Aaron A. Dutton +10
We use the NIHAO simulations to investigate the effects of baryonic physics on the time evolution of Dark Matter central density profiles. The sample is made of indepe…
Expanded haloes, abundance matching and too-big-to-fail in the Local Group
Chris B. Brook, Arianna Di Cintio
Observed kinematical data of 40 Local Group (LG) members are used to derive the dark matter halo mass of such galaxies. Haloes are selected from the theoretically expected LG mass…
A mass-dependent density profile for dark matter haloes including the influence of galaxy formation
Arianna Di Cintio, Chris B. Brook, Aaron A. Dutton +3
We introduce a mass dependent density profile to describe the distribution of dark matter within galaxies, which takes into account the stellar-to-halo mass dependence of the respo…
Galaxy formation
Joseph Silk, Arianna Di Cintio, Irina Dvorkin
Galaxy formation is at the forefront of observation and theory in cosmology. An improved understanding is essential for improving our knowledge both of the cosmological parameters,…
The stellar-to-halo mass relation for Local Group galaxies
C. B. Brook, A. Di Cintio, A. Knebe +4
We contend that a single power law halo mass distribution is appropriate for direct matching to the stellar masses of observed Local Group dwarf galaxies, allowing the determinatio…
The dependence of dark matter profiles on the stellar to halo mass ratio: a prediction for cusps vs cores
Arianna Di Cintio, Chris B. Brook, Andrea V. Maccio +4
We use 31 simulated galaxies from the MaGICC project to investigate the effects of baryonic feedback on the density profiles of dark matter (DM) haloes. The sample covers a wide ma…
Cold versus Warm Dark Matter simulations of a galaxy group
Noam I. Libeskind, Arianna Di Cintio, Alexander Knebe +5
The differences between cold (CDM) and warm (WDM) dark matter in the formation of a group of galaxies is examined by running two identical simulations where in the WDM case the ini…
