List of problems

• 1. Relativistic Astrophysics – black holes • 2. Disc accretion – neutron stars • 3. Supernova explosions• 4. Relic radiation - recombination of the Universe• 5. Nonlinear gravitational instability - Zel’dovich

pancakes• 6. HDM model of the Universe• 7. Magnetic field in the Sun

Standard ΛCDM model

Analysis of the CMB fluctuations shows that

the large scale power spectrum of perturbations is the CDM like one

P(k) ~ kn, n ≈ 0.96 ± 0.007

for r >10Mpc, M > 1013M

B – mode of polarisation, 1403.3985

We show that this dependence cannot be

extended to smaller scales

10-19eV < mdm < 1013eV Six reviews during 2013 year: Feng (2013), Boyarsky et al. (2013), Dreves (2013) Kusenko & Rosenberg (2013), Horiuchi et al. (2013),

Marcovic & Viel (2013).

Three standard problems are discussed: 1. Number of satellites, 2. Core – cusp problem, 3. Ly-α forest. Why they are only qualitative ?

Questions and problems

1. Observed satellites: Ms~ 105 – 107 M, zcr~ 7 –15

Typical mass resolution in simulations M ~ 108 M,

MW-28, A-13

2.Cusp – in simulations of clusters with M > 1013 M, NFW

Core – in LBG – galaxies with M < 109 M

Impact of baryonic component in clusters and galaxies.

3. Ly-α forest: xH~10-5, UV background

Direct and indirect searches DAMA – Bernabei, 2008, 2010

Super CDMS – Agnese 2013

NEGATIVE

Estimates: ms > 13 – 20 keV for WDM

Unstable neutrinos: ms < 3keV

LAC ? X-rays 3.5keV – 73 clusters: (Bulbul et al. 1402.2301)

Decay of DM particles or Ar recombination line

Simulations Maccio 2012 – do not reproduce observations WDM is not a viable solution of the core – cusp

and satellite problems Libeskind 2013 – low mass clouds are not stable

and are expanding Abel (2013) – artefacts appear, filaments

Wang (2013) – unstable DM and Ly-α forest Schultz et al. (1401.3769) – high z Dutton & Maccio (1402.7073) – 17 realizations

Models with one type of DM particles

OUR APPROACHProcess and moment of object formation

Both galaxies and clusters are diversified

steady – state objects.

Global characteristics – mass, angular momentum,.. • Periods of anisotropic compression and/or merging • After virialization the structure of DM halos is frozen. • Therefore we can restore the z of formation

• Zcr – Mvir plane

• Links with the spectrum of perturbations. • Impact of baryonic component

For central regions of the DM halo (Klypin et al. 2011) zcr-Mvir plane
