Dark sector interaction and the supernova absolute magnitude tension

چکیده

It has been intensively discussed if modifications in the dynamics of Universe at late times is able or not to solve $H_0$ tension. On other hand, it also argued that tension actually a on supernova absolute magnitude $M_B$. In this work, we robustly constraint $M_B$ using Pantheon Supernovae Ia (SN) sample, Baryon Acoustic Oscillations (BAO), and Big Bang Nucleosynthesis (BBN) data, assess by comparing three theoretical models, namely standard $\Lambda$CDM, $w$CDM non-gravitational interaction (IDE) between dark energy (DE) matter (DM). We find IDE model can with coupling different from zero 95\% CL, confirming results obtained prior.

Indications of a late-time interaction in the dark sector.

We show that a general late-time interaction between cold dark matter and vacuum energy is favored by current cosmological data sets. We characterize the strength of the coupling by a dimensionless parameter q(V) that is free to take different values in four redshift bins from the primordial epoch up to today. This interacting scenario is in agreement with measurements of cosmic microwave backg...

The Absolute Magnitude of Rr Lyrae

We derive the absolute magnitude of RR Lyrae stars by two independent maximum-likelihood estimations , using Hipparcos proper motion and par-allax data, respectively. By applying the statistical parallax method to 99 Halo RR Lyrae stars, we obtain the mean absolute magnitude < M V > = 0:69 0:10 at ={1.58. Independently of this method, we furthermore derive the M V { Fe/H] relation from H...

How Dark is ‘Dark’? Electromagnetic Interactions in the Dark Sector

We review the physical and cosmological consequences of two possible electromagnetic couplings to the dark sector: (i) a neutral lightest dark-matter particle (LDP) with nonzero electric and/or magnetic dipole moments and (ii) a charged next-to-lightest dark-matter particle (NLDP) which decays to a neutral LDP. For scenario (i) we find that a relatively light particle with mass between a few Me...

Light Chiral Dark Sector

An interesting possibility for dark matter is a scalar particle of mass of order 10 MeV – 1 GeV, interacting with a U(1) gauge boson (dark photon) which mixes with the photon. We present a simple and natural model realizing this possibility. The dark matter arises as a composite pseudo Nambu-Goldstone boson (dark pion) in a non-Abelian gauge sector, which also gives a mass to the dark photon. F...

The Orbital and Absolute Magnitude Distributions of Main Belt Asteroids

We have developed a model-independent analytical method for debiasing the fourdimensional (a, e, i,H) distribution obtained in any asteroid observation program and have applied the technique to results obtained with the 0.9m Spacewatch Telescope. From 1992 to 1995 Spacewatch observed ∼ 3740 deg2 near the ecliptic and made observations of more than 60,000 asteroids to a limiting magnitude of V∼2...
