The BINGO project

open access: yesAstronomy & Astrophysics
Context. Building on the transformative success of optical redshift surveys, the emerging technique of neutral hydrogen (HI) intensity mapping (IM) offers a novel probe of large-scale structure (LSS) growth and the late-time accelerated expansion of the ...

RNA‐Binding Proteins Shape Mammalian Retroelement RNA Fate: Lessons From HIV‐1, LINE‐1, and Related Reverse‐Transcribing Elements

open access: yesAnimal Research and One Health, EarlyView.
RNA‐binding proteins (RBPs) and RNA‐associated factors shape retroelement RNA fate by regulating RNA processing, translation, RNP assembly and remodeling, reverse transcription, nuclear trafficking, chromatin engagement, and RNA surveillance. These pathways balance productive retroviral replication or retrotransposon insertion with RNA decay ...

9. The next telescopes

open access: yes, 2016
Each question that telescopes have helped answer has led to new questions: what is dark matter and dark energy? How did the first galaxies form? Are there habitable, Earth-like exoplanets?

Principal Component‐Based Classification of Blazar Candidates of Uncertain Type in the 4FGL/LAT

open access: yesAstronomische Nachrichten, EarlyView.
ABSTRACT We adopted principal component analysis (PCA), linear discriminant analysis (LDA), and support vector machines (SVM), to study classification for a sample of 2708 Fermi blazars: 1142 BL Lac objects (BLLs), 759 flat spectrum radio quasars (FSRQs), and 807 blazar candidates of uncertain type (BCUs).

The Effelsberg Direct Digitisation radio astronomy back-end framework

open access: yesAstronomy & Astrophysics
Context. Modern digital radio astronomy receivers produce increasingly wide-bandwidth, high bit-rate data streams that necessitate the development of flexible, scalable, and maintainable back-end processing and recording systems.

Overview of the medium and high frequency telescopes of the LiteBIRD space mission [PDF]

open access: yes, 2020
LiteBIRD is a JAXA-led Strategic Large-Class mission designed to search for the existence of the primordial gravitational waves produced during the inflationary phase of the Universe, through the measurements of their imprint onto the polarization of the

Direct SMBH Formation Driven by Runaway Stellar Collisions in Globally Unstable Stellar Systems

open access: yesAstronomische Nachrichten, EarlyView.
ABSTRACT The fueling problem addresses the ultimate fate of the reservoirs of gas and stars driven into the deepest gravitational potential wells of galaxies, thus it may contain the Universe's densest concentrations of gas and stars. This raises a key question: does the infalling material collapse directly into a supermassive black hole, or can it ...

Time-domain photometry and activity evolution of interstellar comet 3I/ATLAS with BHTOM

open access: yesAstronomy & Astrophysics
Context. Time-domain photometric monitoring is essential for characterizing cometary evolution, particularly for rare interstellar objects with limited observing opportunities. Aims.
