Prospects for X-Ray and FUV Observations to Provide Insight Into the “Cepheid Mass Problem”

Frontiers in Astronomy and Space Sciences, 2019
The classical Cepheid Leavitt Law (Period-Luminosity relation) has been known for 100 years, and used in extragalactic distance determination for nearly as long.

Weighing Cosmological Models with SNe Ia and Gamma Ray Burst Redshift Data

Universe, 2019
Many models have been proposed to explain the intergalactic redshift using different observational data and different criteria for the goodness-of-fit of a model to the data. The purpose of this paper is to examine several suggested models using the same

TDCOSMO

Astronomy & Astrophysics
Spatially resolved stellar kinematics has become a key ingredient in time-delay cosmography to break the mass-sheet degeneracy in the mass profile and in turn provide a precise constraint on the Hubble constant and other cosmological parameters.

OB Stars and Cepheids From the Gaia TGAS Catalogue: Test of their Distances and Proper Motions

Open Astronomy, 2017
We consider young distant stars from the Gaia TGAS catalog. These are 250 classical Cepheids and 244 OB stars located at distances up to 4 kpc from the Sun.

A Model-Independent Characterisation of Strong Gravitational Lensing by Observables

Universe, 2019
When light from a distant source object, like a galaxy or a supernova, travels towards us, it is deflected by massive objects that lie in its path. When the mass density of the deflecting object exceeds a certain threshold, multiple, highly distorted ...

AdS scale separation and the distance conjecture

Journal of High Energy Physics, 2023
It has been argued that orientifold vacua with fluxes in type IIA string theory can achieve moduli stabilisation and arbitrary decoupling between the AdS and KK scales upon sending certain unconstrained RR-flux quanta to infinity.

The Depth of the Heavens – Belief and Knowledge During 2500 Years

Open Astronomy, 2003
For Dante Alighieri (1265-1321) the spiritual cosmos contained the Heavens, Earth and Hell, and it was compatible with the physical cosmos known from Aristotle (384-322 B.C.).

Bogardus’s scale of social distance: Advantages and limitations [PDF]

Sociološki Pregled, 2004
Social distance represents one of the oldest, but also of the most current research topics in sociology. Only in the period from 1990 to 1995, more than 500 studies were published about social distance.
