Radio and optical orientations of galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 2009 We investigate the correlations between optical and radio isophotal position angles for 14302 SDSS galaxies with $r$ magnitudes brighter than 18 and which have been associated with extended FIRST radio sources. We identify two separate populations of galaxies using the colour, concentration and their principal components.

Optical and Radio Properties of Extragalactic Sources Observed by the FIRST and SDSS Surveys
, 2002 We discuss the optical and radio properties of 30,000 FIRST sources positionally associated with an SDSS source in 1230 deg$^2$ of sky. The majority (83%) of the FIRST sources identified with an SDSS source brighter than r=21 are optically resolved.

Discovery of rare double-lobe radio galaxies hosted in spiral galaxies [PDF]
, 2015 Double-lobe radio galaxies in the local Universe have traditionally been found to be hosted in elliptical or lenticular galaxies. We report the discovery of four spiral-host double-lobe radio galaxies (J0836+0532, J1159+5820, J1352+3126 and J1649+2635 ...

The Environments of Low and High Luminosity Radio Galaxies at Moderate Redshifts
, 2008 In the local Universe, high-power radio galaxies live in lower density environments than low-luminosity radio galaxies. If this trend continues to higher redshifts, powerful radio galaxies would serve as efficient probes of moderate redshift groups and ...

Associating Fast Radio Bursts with Their Host Galaxies [PDF]
, 2017 The first precise localization of a fast radio burst (FRB) sheds light on the nature of these mysterious bursts and the physical mechanisms that power them.

Compliant Robotics in Space: A Prospective Review of Soft and Deformable Systems for Space Missions
Advanced Intelligent Systems, EarlyView.Compliant robots are increasingly becoming integral to space exploration due to their adaptability, flexibility, and lightweight design. This article reviews categories such as soft, reconfigurable, and hyper‐redundant robots and their evolving role in enhancing space missions.

CHANG-ES IX: Radio scale heights and scale lengths of a consistent sample of 13 spiral galaxies seen edge-on and their correlations [PDF]
, 2017 The vertical halo scale height is a crucial parameter to understand the transport of cosmic-ray electrons (CRE) and their energy loss mechanisms in spiral galaxies.

HI absorption in Radio Galaxies [PDF]
Symposium - International Astronomical Union, 2002 Twenty-two powerful radio galaxies have been searched for HI absorption. We find the highest probability of detecting HI in absorption among narrow-line compact (or small) galaxies or galaxies with indication of richer interstellar medium (i.e. with ongoing or recent star-formation).
