Unveiling the Universe with emerging cosmological probes [PDF]

open access: yesLiving Reviews in Relativity, 2022
The detection of the accelerated expansion of the Universe has been one of the major breakthroughs in modern cosmology. Several cosmological probes (Cosmic Microwave Background, Supernovae Type Ia, Baryon Acoustic Oscillations) have been studied in depth

The Pantheon+ Analysis: Cosmological Constraints [PDF]

open access: yesAstrophysical Journal, 2022
We present constraints on cosmological parameters from the Pantheon+ analysis of 1701 light curves of 1550 distinct Type Ia supernovae (SNe Ia) ranging in redshift from z = 0.001 to 2.26.

The Atacama Cosmology Telescope: DR6 Gravitational Lensing Map and Cosmological Parameters [PDF]

open access: yesAstrophysical Journal, 2023
We present cosmological constraints from a gravitational lensing mass map covering 9400 deg2 reconstructed from measurements of the cosmic microwave background (CMB) made by the Atacama Cosmology Telescope (ACT) from 2017 to 2021.

Cosmology Intertwined: A Review of the Particle Physics, Astrophysics, and Cosmology Associated with the Cosmological Tensions and Anomalies [PDF]

open access: yesJournal of High Energy Astrophysics, 2022
In this paper we will list a few important goals that need to be addressed in the next decade, also taking into account the current discordances between the different cosmological probes, such as the disagreement in the value of the Hubble constant $H_0$,

Sudûr Kozmolojisi: Fârâbî ve İbn Sînâ Arasındaki Farklar Üzerine Bir Değerlendirme

open access: yesTürkiye Din Eğitimi Araştırmaları Dergisi, 2022
Fârâbî ve İbn Sînâ’nın Aristotelesçi akıl görüşü üzerine inşa ettikleri sudûr teorisinin metafiziksel anlamda birlik ve çokluk ilişkisini açıklamasının bir yönü de varlık anlamının ve hareketin aşağıdaki mevcutlara aktarılmasını tutarlı bir şekilde ...

Observational Evidence from Supernovae for an Accelerating Universe and a Cosmological Constant [PDF]

open access: yes, 1998
We present spectral and photometric observations of 10 Type Ia supernovae (SNe Ia) in the redshift range 0.16 ≤ z ≤ 0.62. The luminosity distances of these objects are determined by methods that employ relations between SN Ia luminosity and light curve ...

Estimating COVID-19 mortality in Italy early in the COVID-19 pandemic

open access: yesNature Communications, 2021
Estimates of COVID-19-related mortality are limited by incomplete testing. Here, the authors perform counterfactual analyses and estimate that there were 59,000–62,000 deaths from COVID-19 in Italy until 9th September 2020, approximately 1.5 times higher

SEVEN-YEAR WILKINSON MICROWAVE ANISOTROPY PROBE (WMAP) OBSERVATIONS: COSMOLOGICAL INTERPRETATION [PDF]

open access: yes, 2010
The combination of seven-year data from WMAP and improved astrophysical data rigorously tests the standard cosmological model and places new constraints on its basic parameters and extensions.

First-Year Wilkinson Microwave Anisotropy Probe (WMAP) Observations: Determination of Cosmological Parameters [PDF]

open access: yes, 2003
WMAP precision data enable accurate testing of cosmological models. We find that the emerging standard model of cosmology, a flat Λ-dominated universe seeded by a nearly scale-invariant adiabatic Gaussian fluctuations, fits the WMAP data.
