Unification of Radio Galaxies and their Accretion Jet Properties [PDF]
Journal of Astrophysics and Astronomy, 2011 We investigate the relation between black hole mass, M_bh, and jet power, Q_jet, for a sample of BL Lacs and radio quasars. We find that BL Lacs are separated from radio quasars by the FR I/II dividing line in M_bh-Q_jet plane, which strongly supports the unification scheme of FR I/BL Lac and FR II/radio quasar.

Rising jet-inflated bubbles in clusters of galaxies [PDF]
Monthly Notices of the Royal Astronomical Society: Letters, 2008 Abstract We conduct two-dimensional axisymmetric (referred to as 2.5D) hydrodynamical numerical simulations of bubble evolution in clusters of galaxies. We inflate bubbles using slow, massive jets with a wide opening angle, and follow their evolution as they rise through the intracluster medium.

Face‐on Dust Disks in Galaxies with Optical Jets
The Astrophysical Journal, 2000 The presence of optical synchrotron jets in radio galaxies is relatively rare. Here, we show that of the nearest five FR-I 3CR radio galaxies showing optical jets, {\it four} show evidence for almost circular, presumably face-on, dust disks. This is strong support for the two-fold idea that (\romannumeral1) jets emerge close to perpendicular to inner ...

Jets, bubbles, and heat pumps in galaxy clusters [PDF]
Monthly Notices of the Royal Astronomical Society, 2019 Abstract Feedback from active galactic nucleus (AGN) jets has been proposed to counteract the catastrophic cooling in many galaxy clusters. However, it is still unclear which physical processes are acting to couple the energy from the bi-directional jets to the intra-cluster medium (ICM).

Advanced Science, EarlyView.ABSTRACT The multifunctional integration of chips with high flexibility and scalable manufacturing is crucial for enhancing chip performance, reducing chip size, and simplifying chip design. However, balancing volume, cost, flexibility, and functionality using traditional heterogeneous integration methods is challenging.

Optical polarimetry studies of Seyfert galaxies [PDF]
, 1999 Optical imaging polarimetry has been performed on seven nearby Seyfert galaxies, three with face-on and four with edge-on host galaxies of various morphological classifications.

Superdiscs in radio galaxies: jet–wind interactions [PDF]
Monthly Notices of the Royal Astronomical Society, 2007 Taking a clue from their sharp-edged (strip-like) morphology observed in several cases, a new mechanism is proposed for the formation of the emission gaps seen between the radio lobes of many powerful extragalactic double radio sources. Canonical understanding of the radio gaps invokes either blocking of the back-flowing lobe plasma by the denser ...

Utopia Remembers: The Soviet Past in the Imagined Communist Future
The Russian Review, EarlyView.Abstract After a twenty‐five‐year hiatus, the reappearance of utopian literature in 1957 prompted Soviet literary watchdogs to corral the subgenre into an ideologically‐acceptable mold. A key requirement was for future generations to be depicted as reverently commemorating the past.

FR II radio galaxies with z < 0.3 I. Properties of jets, cores and hotspots [PDF]
, 1998 In previous papers we have discussed high-resolution observations of a large sample of powerful radio galaxies with z < 0.3. Jets are detected in up to 80 per cent of the sample, and radio cores in nearly all the objects; in addition, we are able to ...

, 2020 This thesis describes two studies of extragalactic radio sources at high resolution and sensitivity. Most of the well-known facts about radio sources come from low-resolution imaging, despite the fact that much of the interesting physics (that of the jets and hotspots) occurs on scales that are small compared to the overall source size.
