Massive galaxies with very young AGN

, 2007
Gigahertz Peaked Spectrum (GPS) radio galaxies are generally thought to be the young counterparts of classical extended radio sources and live in massive ellipticals.

Deep Chandra Observations of NGC 5728. III. Probing the High-resolution X-Ray Morphology and Multiphase Interstellar Medium Interactions in the Circumnuclear Region

The Astrophysical Journal
We present a detailed imaging analysis of 260 ks of subarcsecond resolution Chandra (ACIS-S) observations of the nearby Seyfert 2 galaxy NGC 5728. Our study focuses on the bright and diffuse soft X-ray emission within the galaxy's inner ∼1 kpc.

JWST Insights into Narrow-line Little Red Dots

The Astrophysical Journal
JWST has revealed a population of red and compact objects with unique “V-shaped” spectral energy distributions (SEDs) known as “Little Red Dots” (LRDs). Many LRDs exhibit broad Balmer lines and thus likely host active galactic nuclei (AGNs).

A New Approach to Constraining Properties of Active Galactic Nucleus Host Galaxies by Combining Image and Spectral Energy Distribution Decomposition: Testing upon the MBH–M⋆ Relation

The Astrophysical Journal
The outshining light from active galactic nuclei (AGNs) poses significant challenges in studying the properties of AGN host galaxies. To address this issue, we propose a novel approach that combines image decomposition and spectral energy distribution ...
