Parametric Design of Continuum Robots Using Interlocking Ball Joints

open access: yesAdvanced Intelligent Systems, EarlyView.
Herein, a parametric design methodology is introduced for producing a wide variety of modular ball joint‐based continuum robots. It is demonstrate by designing a magnetically actuated continuum robot for cardiac ablations. The methodology is released as an open‐source computer‐assisted design extension that automatically designs continuum robots based ...

Radio continuum and far-infrared emission from the galaxies in the Eridanus group

open access: yes, 2005
The Eridanus galaxies follow the well-known radio-FIR correlation. Majority (70%) of these galaxies have their star formation rates below that of the Milky Way.

Optical Properties of Radio-selected Narrow Line Seyfert 1 Galaxies [PDF]

open access: yes, 2006
We present results from the analysis of the optical spectra of 47 radio-selected narrow-line Seyfert 1 galaxies (NLS1s). These objects are a subset of the First Bright Quasar Survey (FBQS) and were initially detected at 20 cm (flux density limit ~1 mJy ...

Mutual distance dependence drives the observed jet-power–radio-luminosity scaling relations in radio galaxies [PDF]

open access: yes, 2015
The kinetic power of radio jets is a quantity of fundamental importance to studies of the AGN feedback process and radio galaxy physics. A widely used proxy for jet power is the extended radio luminosity.

Highest redshift radio galaxies [PDF]

open access: yesSPIE Proceedings, 2000
At low redshifts powerful radio sources are uniquely associated with massive galaxies, and are thought to be powered by supermassive black holes. Modern 8m -- 10m telescopes may be used used to find their likely progenitors at very high redshifts to study their formation and evolution.

Dwarf Galaxies with Radio-excess Active Galactic Nuclei in the Very Large Array Sky Survey

open access: yesThe Astrophysical Journal
We present a systematic search for radio active galactic nuclei (AGNs) in dwarf galaxies using recent observations taken by the Very Large Array Sky Survey (VLASS).

Pair-Matching of Radio-Loud and Radio-Quiet AGNs

open access: yesFrontiers in Astronomy and Space Sciences, 2017
Active galactic nuclei (AGNs) are known to cover an extremely broad range of radio luminosities and the spread of their radio-loudness is very large at any value of the Eddington ratio.

Cosmic ray acceleration to ultrahigh energy in radio galaxies [PDF]

open access: yesEPJ Web of Conferences, 2019
The origin of ultrahigh energy cosmic rays (UHECRs) is an open question. In this proceeding, we first review the general physical requirements that a source must meet for acceleration to 10-100 EeV, including the consideration that the shock is not ...

Effect of Background Magnetic Field on Ion Weibel Instability With High‐Intensity Short‐Pulse Lasers

open access: yesContributions to Plasma Physics, EarlyView.
ABSTRACT The effect of finite background magnetic field on magnetic field amplification by Weibel instability using high‐intensity short‐pulse lasers is investigated. We consider Weibel instability for counter‐streaming sub‐relativistic plasma flows generated by shooting pure carbon targets with short‐pulse lasers.
