A generic tired-light mechanism is examined in which a photon, like any particle moving in a medium, experiences friction, that is, a force resisting its motion. If the velocity of light is assumed to be constant, this hypothesis yields a Hubble-like law which is also a consequence of the Rh = ct cosmology. Herein, it is used for estimating matter density as a function of redshift, allowing to show that the density of sources of long gamma-ray bursts appears to be nearly constant, up to z ≈ 4…

According to a tired-light cosmological model where H(z) = H(0) (1 + z), the number density of galaxies has been nearly constant over the last 10 Gyr, at least, meaning that, as far as galaxies are
No obvious change in the number density of galaxies up to z ≈ 3.5
The analysis of the cumulative count of sources of gamma-ray bursts as a function of their redshift strongly suggests that the number density of star-forming galaxies is roughly constant, up to z ≈

A simple Hubble-like law in lieu of dark energy
Within the frame of thecold dark matter paradigm, a dark energy component of unknown origin is expected to represent nearly 70% of the en- ergy of the Universe. Herein, a non-standard form of the

Time Dilation in the Light Curve of the Distant Type Ia Supernova SN 1995K
The light curve of a distant Type Ia supernova acts like a clock that can be used to test the expansion of the universe. SN 1995K, at a spectroscopic redshift of z = 0.479, provides one of the first

TLDR
Some of the principal facts which any cosmological theory will have to account for are pointed out and a new effect of masses upon light will be suggested which is a sort of gravitational analogue of the Compton effect.

We examine the effects of time dilation on the temporal profiles of gamma-ray burst (GRB) pulses. By using prescriptions for the shape and evolution of prompt gamma-ray spectra, we can generate a

One of the most compelling tasks of modern cosmology is to constrain the expansion history of the Universe, since this measurement can give insights on the nature of dark energy and help to estimate

TLDR
A re-examination of the question of the motion of the sun with respect to the extra-galactic nebulae, based on only those nebular distances which are believed to be fairly reliable, indicates the probability of an approximately uniform upper limit to the absolute luminosity of stars, in the late-type spirals and irregular neBulae at least.
CDM accelerating cosmology as an alternative to ΛCDM model
A new accelerating cosmology driven only by baryons plus cold dark matter (CDM) is proposed in the framework of general relativity. In this scenario the present accelerating stage of the Universe is

ABSTRACT The use of luminous red galaxies as cosmic chronometers provides us with an in-dispensable method of measuring the universal expansion rate H(z) in a model-independent way. Unlike many
