A Candidate Dual Active Galactic Nucleus At Z=1.175 [PDF]
, 2012 The X-ray source CXOXBJ142607.6+353351 (CXOJ1426+35), which was identified in a 172 ks Chandra image in the Bootes field, shows double-peaked rest-frame optical/UV emission lines, separated by 0.''69 (5.5 kpc) in the spatial dimension and by 690 km s(-1)

X-ray Photons in the CO 2-1 'Lacuna' of NGC 2110
, 2019 A recent ALMA study of the Seyfert 2 Active Galactic Nucleus (AGN) NGC 2110 by Rosario et al. (2019) has reported a remarkable lack of CO 2-1 emission from the circumnuclear region, where optical lines and H2 emission are observed, leading to the ...

Modeling the Spectral Energy Distribution of the Active Galactic Nucleus inside NGC 4395
The Astrophysical Journal, 2023 We study the broadband spectral energy distribution (SED) of the prototypical low-mass active galactic nucleus (AGN) in NGC 4395. We jointly model the optical through mid-IR SED with a combination of galaxy and AGN light, and find that on arcsecond ...

X-Ray Flares in the Long-term Light Curve of Low-luminosity Active Galactic Nucleus M81*
The Astrophysical Journal, 2023 Most active galactic nuclei at the center of the nearby galaxies have supermassive black holes accreting at sub-Eddington rates through hot accretion flows or radiatively inefficient accretion flows, which efficiently produce jets.

Enhanced Black Hole Mergers in Active Galactic Nucleus Disks due to Precession-induced Resonances
The Astrophysical Journal, 2023 Recent studies have shown that active galactic nucleus (AGN) disks can host sources of gravitational waves. Compact binaries can form and merge in AGN disks through their interactions with the gas and other compact objects in the disk.

The Accuracy of Morphological Decomposition of Active Galactic Nucleus Host Galaxies
, 2008 In order to assess the accuracy with which we can determine the morphologies of AGN host galaxies, we have simulated more than 50,000 ACS images of galaxies with z < 1.25, using image and noise properties appropriate for the GOODS survey.

Advanced Engineering Materials, EarlyView.Mesoporous bioactive glass nanoparticles (MBGNs) are investigated for bone regeneration given their remarkable structural and functional properties. MBGNs are functionalized with Mn and Cu and incorporated with quercetin, a natural flavonoid exhibiting antioxidant, anti‐inflammatory, and antimicrobial properties.

Spectrally Tunable 2D Material‐Based Infrared Photodetectors for Intelligent Optoelectronics
Advanced Functional Materials, EarlyView.Intelligent optoelectronics through spectral engineering of 2D material‐based infrared photodetectors. Abstract The evolution of intelligent optoelectronic systems is driven by artificial intelligence (AI). However, their practical realization hinges on the ability to dynamically capture and process optical signals across a broad infrared (IR) spectrum.

VLBI Observations of NGC6240: resolving the double nuclei and radio supernovae
, 2011 The European VLBI Network (EVN) has been used at two epochs in 2003 and 2009 to obtain multi-frequency high-resolution images of the merger galaxy NGC6240 in order to study the radio properties of all compact high-brightness components in the galaxy. Our

Advanced Materials, EarlyView.All‐perovskite tandem solar cells are evaluated under low‐intensity and low‐temperature (LILT) conditions relevant to space environments. Distinct loss regimes emerge, where weaker entropic mixing causes halide segragation below ≈240 K going along with a strong current imbalance, while poor electron transport in C60 dominates.
