Reparametrization Invariance and the Schrödinger Equation
V. I. Tkach, A. Pashnev, J. J. Rosales
In the present work we consider a time-dependent Schrödinger equation for systems invariant under the reparametrization of time. We develop the two-stage procedure of construction…
Low frequency catalogues of the CATS database
O. V. Verkhodanov, S. A. Trushkin, H. Andernach
The authors describe the largest existing publicly accessible radio source database CATS (``astrophysical CATalogues Supporting system''; http://cats.sao.ru). CATS contains more th…
The problem of identifying decametric sources
O. V. Verkhodanov, H. Andernach, N. V. Verkhodanova
We describe a method to construct continuum spectra for radio sources on the basis of entries from various source catalogues in comparatively large error boxes around a given sky p…
Supersymmetric Quantum Mechanics for Bianchi Class A models
J. Socorro, E. R. Medina
In this work we present cosmological quantum solutions for all Bianchi Class A cosmological models obtained by means of supersymmetric quantum mechanics . We are able to write one…
Hydrogen atom as an eigenvalue problem in 3D spaces of constant curvature and minimal length
L. M. Nieto, H. C. Rosu, M. Santander
An old result of A.F. Stevenson [Phys. Rev.} 59, 842 (1941)] concerning the Kepler-Coulomb quantum problem on the three-dimensional (3D) hypersphere is considered from the perspect…
Mapping the Hidden Universe: The Galaxy Distribution in the Zone of Avoidance
Renee C. Kraan-Korteweg, Sebastian Juraszek
Due to the foreground extinction of the Milky Way, galaxies become increasingly faint as they approach the Galactic Equator creating a ``zone of avoidance'' (ZOA) in the distributi…
A Catalog of Galaxies behind the Southern Milky Way. - I. The Hydra/Antlia Extension (l: 266 - 296 deg)
Renee C. Kraan-Korteweg
A deep optical galaxy search in the southern Milky Way - aimed at reducing the width of the Zone of Avoidance - revealed 3279 galaxy candidates above the diameter limit of D > 0.2…
Weyl anomaly from Weyl gravity
Shin'ichi Nojiri, Sergei D. Odintsov
We calculate the conformal anomaly from 5d Weyl gravity (with broken conformal symmetry) which is conjectured to be supergravity dual to superconformal field theory vi…
Blind spot may reveal vacuum radiation
H. C. Rosu
This is a Physics World features paper on Chen-Tajima proposal to detect Unruh radiation by means of high-intensity lasers (PRL 83, 256 (1999)).
Quantum mechanical spectral engineering by scaling intertwining
D. J. Fernandez C., H. C. Rosu
Using the concept of spectral engineering we explore the possibilities of building potentials with prescribed spectra offered by a modified intertwining technique involving operato…
The Extreme Scattering Event Toward PKS 1741-038: VLBI Images
T. Joseph W. Lazio, A. L. Fey, Brian Dennison
(Abridged) We report multi-epoch VLBI observations of the source PKS 1741-038 as it underwent an extreme scattering event. Observations at four epochs were obtained, and images wer…
Quantisation without Gauge Fixing: Avoiding Gribov Ambiguities through the Physical Projector
Victor M. Villanueva, Jan Govaerts, Jose-Luis Lucio-Martinez
The quantisation of gauge invariant systems usually proceeds through some gauge fixing procedure of one type or another. Typically for most cases, such gauge fixings are plagued by…
The supercluster-void network V. Alternative evidence for its regularity
O. Toomet, H. Andernach, J. Einasto +4
The distribution of Abell clusters of galaxies is analysed to study the regularity of the supercluster-void network. A new geometric method sensitive to the regularity of the locat…
Unified approach to study quantum properties of primordial black holes, wormholes and of quantum cosmology
S. Nojiri, O. Obregon, S. D. Odintsov
We review the anomaly induced effective action for dilaton coupled spinors and scalars in large N and s-wave approximation. It may be applied to study the following fundamental pro…
Study of the interacting system NGC 6845
Irapuan Rodrigues, Horacio Dottori, Elias Brinks +1
We present optical spectroscopy, B, V, R and I CCD photometry and VLA neutral hydrogen observations of the interacting quartet NGC 6845, also know as Klemola 30. NGC 6845 A, the do…
New Galaxies Discovered in the First Blind HI Survey of the Centaurus A Group
G. D. Banks, M. J. Disney, P. M. Knezek +26
We have commenced a 21-cm survey of the entire southern sky (δ< 0 degrees, -1200 km/s < v < 12700 km/s) which is ''blind'', i.e. unbiased by previous optical information. In the pr…
Generalized Reissner-Nordström solution in Metric-Affine Gravity
Alfredo Macías, José Socorro
We present the generalized Reissner-Nordström solution of the field equations of metric-affine gravity (MAG), endowed with electric and magnetic charges, as well as with gravito-el…
Remarks on 2+1 Self-dual Chern-Simons Gravity
H. Garcia-Compean, O. Obregon, C. Ramirez +1
We study 2+1 Chern-Simons gravity at the classical action level. In particular we rederive the linear combinations of the ``standard'' and ``exotic'' Einstein actions, from the (an…
Neutral Hydrogen (21 cm) Absorption in Seyfert Galaxies: Evidence for Free-free Absorption and Sub-kiloparsec Gaseous Disks
J. F. Gallimore, S. A. Baum, C. P. O'Dea +2
Active galaxies are thought to be both fueled and obscured by neutral gas removed from the host galaxy and funneled into a central accretion disk. We performed a VLA imaging survey…
Relativistic quantum field inertia and vacuum field noise spectra
