Double-Double Radio Galaxies: A New Accretion Model

Published:Dec 26, 2025 23:47
1 min read
ArXiv

Analysis

This paper proposes a novel model for the formation of double-double radio galaxies (DDRGs), suggesting that the observed inner and outer jets are linked by continuous accretion, even during the quiescent phase. The authors argue that the black hole spin plays a crucial role, with jet formation being dependent on spin and the quiescent time correlating with the subsequent jet duration. This challenges the conventional view of independent accretion events and offers a compelling explanation for the observed correlations in DDRGs.
Reference

“The authors show that a correlation between the quiescent time and the inner jet time may exist, which they interpret as resulting from continued accretion through the quiescent jet phase.”

The impact of selection criteria on the properties of green valley galaxies

ArXiv

Analysis

This article likely explores how the methods used to identify and select green valley galaxies (galaxies in a transitional phase between active star formation and quiescence) influence the observed characteristics of these galaxies. The research probably investigates biases introduced by specific selection criteria and their effects on derived properties like stellar mass, star formation rate, and morphology. The source, ArXiv, suggests this is a peer-reviewed or pre-print scientific publication.

    “Further analysis would require reading the actual paper to understand the specific selection criteria examined and the conclusions drawn regarding their impact.”
