Testing CCC+TL Cosmology with Observed Baryon Acoustic Oscillation Features

The Astrophysical Journal
The primary purpose of this paper is to see how well a recently proposed new model fits (a) the position of the baryon acoustic oscillation (BAO) features observed in the large-scale distribution of galaxies and (b) the angular size measured for the ...

Enhanced Tidal Mixing Strengthened and Stabilized the AMOC During the Bølling–Allerød

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Proxy records indicate a robust Atlantic Meridional Overturning Circulation (AMOC) during the Bølling–Allerød (BA) interstadial, despite substantial meltwater discharge. Using ocean circulation simulations, we demonstrate that enhanced tidal mixing, sustained by lower‐than‐modern sea levels, significantly strengthens the BA AMOC and increases ...

Analysis of Polarized Dust Emission Using Data from the First Flight of SPIDER

The Astrophysical Journal
Using data from the first flight of Spider and from the Planck High Frequency Instrument, we probe the properties of polarized emission from interstellar dust in the Spider observing region.

On observations of the cosmic radiation background

The Astrophysical Journal, 1980
Extant models to explain the observed anisotropies in the microwave and x-radiation background have been of the clump type: the earth is falling toward a density enhancement of large scale in an otherwise homogeneous cosmology. We present here alternate models in which the anisotropies are true relics of the very early history of the universe, and in ...

Physics‐Embedded Deep Learning Reveals the Memory Effect of Ionospheric Electron Density in Response to Solar EUV Forcing

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Precise characterization of the electron density profile is crucial for optimizing high frequency communications. Reconstruction models often assume an instantaneous ionospheric response to solar forcing or using time delays, neglecting the time‐integrated cumulative “memory effect” of plasma dynamics.

The Cosmic Infrared Background Experiment-2: An Intensity-mapping Optimized Sounding-rocket Payload to Understand the Near-IR Extragalactic Background Light

The Astrophysical Journal Supplement Series
The background light produced by emission from all sources over cosmic history is a powerful diagnostic of structure formation and evolution. At near-infrared wavelengths, this extragalactic background light (EBL) is comprised of emission from galaxies ...

Cosmic archeology with the Cosmic Microwave Background Radiation

, 2010
A cosmologia é uma ciência relativamente jovem, e que permanentemente requer observações que sustentem as previsões teóricas dos cientistas que trabalham nessa área. A Radiação Cósmica de Fundo em microondas (RCFM) é uma das observações utilizadas para isso, sendo a mais antiga fonte de observação direta do Universo de que dispomos e uma evidência ...

Foreground Removal in Ground-based CMB Observations Using a Transformer Model

The Astrophysical Journal Supplement Series
We present a novel method for cosmic microwave background (CMB) foreground removal based on deep learning techniques. This method employs a Transformer model, referred to as TCMB , which is specifically designed to effectively process HEALPix-format ...
