Halo mass functions in mixed cold and fuzzy dark matter models
Sarah C. Johnston, Simon May, Tibor Dome +5
We investigate the impact of mixed cold and fuzzy dark matter (MDM) cosmologies on the halo mass function (HMF) using numerical simulations performed with the AxiREPO framework. We…
The Impact of Fuzzy Dark Matter Dynamics on the Accumulation and Fragmentation of Primordial Gas
Alexander Tocher, Anastasia Fialkov, Simon May +4
Fuzzy Dark Matter (FDM), particularly in the eV mass regime is frequently used to characterize wave-like interference effects. It exhibits macroscopic wave properties, w…
Increased Burstiness at High Redshift in Multi-Physics Models Combining Supernova Feedback, Radiative Transfer and Cosmic Rays
Tibor Dome, Sergio Martin-Alvarez, Sandro Tacchella +2
We study star formation variability, or burstiness, as a method to constrain and compare different galaxy formation models at high redshift using the Azahar simulation suite. The m…
Improved Halo Model Calibrations for Mixed Dark Matter Models of Ultralight Axions
Tibor Dome, Simon May, Alex Laguë +5
We study the implications of relaxing the requirement for ultralight axions to account for all dark matter in the Universe by examining mixed dark matter (MDM) cosmologies with axi…
Modeling Post-Reionization HI Distributions in Fuzzy Dark Matter Cosmologies Using Conditional Normalizing Flows
Tibor Dome, Rumail Azhar, Anastasia Fialkov
Upcoming 21 cm intensity mapping experiments like the Square Kilometer Array (SKA) hold significant potential to constrain the properties of dark matter. In this work, we model neu…
Linear rotor in an ideal Bose gas near the threshold for binding
Tibor Dome, Artem G. Volosniev, Areg Ghazaryan +3
We study a linear rotor in a bosonic bath within the angulon formalism. Our focus is on systems where isotropic or anisotropic impurity-boson interactions support a shallow bound s…
Mini-quenching of galaxies by bursty star formation
Tibor Dome, Sandro Tacchella, Anastasia Fialkov +5
The recent reported discovery of a low-mass and an intermediate-mass quenched galaxy with JWST/NIRSpec is the first evidence of halted star formation above $z\appro…
Cosmological Structure Formation and Soliton Phase Transition in Fuzzy Dark Matter with Axion Self-Interactions
Philip Mocz, Anastasia Fialkov, Mark Vogelsberger +11
We investigate cosmological structure formation in Fuzzy Dark Matter (FDM) with an attractive self-interaction (SI) with numerical simulations. Such a SI would arise if the FDM bos…
Cosmic Web Dissection in Fuzzy Dark Matter Cosmologies
Tibor Dome, Anastasia Fialkov, Nina Sartorio +1
On large cosmological scales, anisotropic gravitational collapse is manifest in the dark cosmic web. Its statistical properties are little known for alternative dark matter models…
On the Cosmic Web Elongation in Fuzzy Dark Matter Cosmologies: Effects on Density Profiles, Shapes and Alignments of Halos
Tibor Dome, Anastasia Fialkov, Philip Mocz +3
The fuzzy dark matter (FDM) scenario has received increased attention in recent years due to the small-scale challenges of the vanilla Lambda cold dark matter (CDM) cosmological…
