Modeling the Broad-Band Emission from the Gamma-Ray Emitting Narrow-Line Seyfert-1 Galaxies 1H 0323+342 and B2 0954+25A

Frontiers in Astronomy and Space Sciences, 2017
Prior to the Fermi-LAT era, only two classes of Active Galactic Nuclei (AGN) were thought to harbor relativistic jets that radiate up to gamma-ray energies: blazars and radio galaxies. The detection of variable gamma-ray emission from Narrow Line Seyfert

Predicting the Yields of z > 6.5 Quasar Surveys in the Era of Roman and Rubin

The Astrophysical Journal, 2023
About 70 luminous quasars discovered at z > 6.5 are strongly biased toward the bright end, thus not providing a comprehensive view of quasar abundance beyond the cosmic dawn. We present the predicted results of the Roman/Rubin high-redshift quasar survey,

Material Strategies for Stimulation and Recording in Neural Biocomputing Platforms

Advanced Electronic Materials, EarlyView.
Material strategies enabling stimulation and recording are central to neural biocomputing systems. This review examines how electronic materials govern the encoding of inputs and decoding of outputs in living neural networks. Advances in electrical, optical, and multimodal interfaces highlight emerging design principles for biocomputing platforms ...

Large SDSS quasar groups and their statistical significance

, 2015
We use a volume-limited sample of quasars in the Sloan Digital Sky Survey (SDSS) DR7 quasar catalog to identify quasar groups and address their statistical significance.

Red Companions to a z=2.15 Radio Loud Quasar [PDF]

, 1999
We have conducted observations of the environment around the z=2.15 radio loud quasar 1550-269 in search of distant galaxies associated either with it or the z=2.09 CIV absorber along its line of sight.

Minimalist Footwear Acutely Alters Running Kinematics in Runners With Medial Tibial Stress Syndrome

Arthroscopy, Sports Medicine, and Rehabilitation, EarlyView.
Purpose To assess immediate biomechanical changes in runners with medial tibial stress syndrome (MTSS) when transitioning from standard to minimalist running shoes. Methods Active runners diagnosed with MTSS ran on a treadmill at 10 km/h using standard and minimalist running shoes. Hip, knee, and ankle joint kinematics were captured using a 16‐infrared‐

MEASURING THE TIME DELAYS IN GRAVITATIONALLY LENSED QUASARS IN THE PRESENCE OF MICROLENSING

Radio Physics and Radio Astronomy, 2014
A method to measure the time delays in gravitationally lensed quasars is proposed, which provides a simple and transparent procedure to eliminate the effects of microlensing events.

Feasibility Study for Application of Digitized Henize Mt. Wilson Michigan Southern Sky Hα$$ \boldsymbol{\alpha} $$ Survey Low‐Dispersive Spectral Plates for Searches for Anomalous and Highly Redshifted Objects

Astronomische Nachrichten, EarlyView.
ABSTRACT The goal of this study is to confirm the feasibility of the use of digitized low dispersive MtWilson Michigan Southern Sky Hα$$ \alpha $$ survey astronomical photographic plates for modern astrophysical research. The detection of highly redshifted objects, such as early galaxies and quasars, is fundamental to understanding the universe's ...

Think Outside the Color Box: Probabilistic Target Selection and the SDSS-XDQSO Quasar Targeting Catalog

, 2011
We present the SDSS-XDQSO quasar targeting catalog for efficient flux-based quasar target selection down to the faint limit of the Sloan Digital Sky Survey (SDSS) catalog, even at medium redshifts (2.5
