On the road to percent accuracy: nonlinear reaction of the matter power spectrum to dark energy and modified gravity
Matteo Cataneo, Lucas Lombriser, Catherine Heymans +4
We present a general method to compute the nonlinear matter power spectrum for dark energy and modified gravity scenarios with percent-level accuracy. By adopting the halo model an…
ETHOS - an Effective Theory of Structure Formation: detecting dark matter interactions through the Lyman- forest
Sownak Bose, Mark Vogelsberger, Jesús Zavala +4
We perform a series of cosmological hydrodynamic simulations to investigate the effects of non-gravitational dark matter (DM) interactions on the intergalactic medium (IGM). In par…
The signal of decaying dark matter with hydrodynamical simulations
Mark R. Lovell, David Barnes, Yannick Bahé +11
Dark matter particles may decay, emitting photons. Drawing on the EAGLE family of hydrodynamic simulations of galaxy formation -- including the APOSTLE and C-EAGLE simulations -- w…
No cores in dark matter-dominated dwarf galaxies with bursty star formation histories
Sownak Bose, Carlos S. Frenk, Adrian Jenkins +10
Measurements of the rotation curves of dwarf galaxies are often interpreted as requiring a constant density core at the centre, at odds with the "cuspy" inner profiles predicted by…
The Santiago-Harvard-Edinburgh-Durham void comparison II: unveiling the Vainshtein screening using weak lensing
Enrique Paillas, Marius Cautun, Baojiu Li +4
We study cosmic voids in the normal-branch Dvali-Gabadadze-Porrati (nDGP) braneworld models, which are representative of a class of modified gravity theories where deviations from…
A redshift-independent efficiency model: star formation and stellar masses in dark matter halos at z>4
Sandro Tacchella, Sownak Bose, Charlie Conroy +2
We explore the connection between the UV luminosity functions (LFs) of high- galaxies and the distribution of stellar masses and star-formation histories (SFHs) in their host da…
