Singularity Avoidance in Gravitational Collapse of an Inhomogeneous Fluid in Rastall Gravity
Akbar Jahan, Halime Miraghaei, Shayesteh Ghaffari +1
Various types of inhomogeneous collapse models in general relativity (GR) lead to the formation of spacetime singularities either visible or hidden by a spacetime horizon. Our aim…
The LOFAR Two-metre Sky Survey Deep Fields Data Release 1: V. Survey description, source classifications and host galaxy properties
P. N. Best, R. Kondapally, W. L. Williams +26
Source classifications, stellar masses and star formation rates are presented for 80,000 radio sources from the first data release of the Low Frequency Array Two-metre Sky Survey (…
Exploring the Fundamental Mechanism in Driving Highest-velocity Ionized Outflows in Radio AGNs
Ashraf Ayubinia, Yongquan Xue, Jong-Hak Woo +4
We investigate the ionized gas kinematics relationship with X-ray, radio and accreting properties using a sample of 348 nearby () SDSS-FIRST-X-ray detected AGNs. X-ray pro…
The relation between the radio emission of the core and host galaxy properties in Fanaroff-Riley type II radio galaxies
F. Mazoochi, H. Miraghaei, N. Riazi
We study the radio power of the core and its relation to the optical properties of the host galaxy in samples of high excitation (HERG) and low excitation (LERG) Fanaroff-Riley typ…
The interstellar medium in the environment of the supernova-less long-duration GRB 111005A
Aleksandra Leśniewska, M. J. Michałowski, P. Kamphuis +17
Long ( s) gamma ray bursts (GRBs) are associated with explosions of massive stars, although in three instances, supernovae (SNe) have not been detected, despite deep observatio…
No dependence of radio properties of brightest group galaxies on the luminosity gap
H. Miraghaei, P. N. Best, R. K. Cochrane +1
We study the radio and optical properties of the brightest group galaxies (BGGs) in a sample of galaxy groups from the SDSS DR7. The luminosity difference between the BGG and the s…
The effect of environment on AGN activity: the properties of radio and optical AGN in void, isolated and group galaxies
Halime Miraghaei
The evolution of galaxies depends on their environments. In this work, active galactic nucleus (AGN) activity in different environments has been studied. The fractions of radio and…
Galaxy And Mass Assembly (GAMA): 'No Smoking' zone for giant elliptical galaxies?
Habib G. Khosroshahi, Mojtaba Raouf, Halime Miraghaei +8
We study the radio emission of the most massive galaxies in a sample of dynamically relaxed and un-relaxed galaxy groups from Galaxy and Mass Assembly (GAMA). The dynamical state o…
The nuclear properties and extended morphologies of powerful radio galaxies: the roles of host galaxy and environment
H. Miraghaei, P. N. Best
Powerful radio galaxies exist as either compact or extended sources, with the extended sources traditionally classified by their radio morphologies as Fanaroff--Riley (FR) type I a…
AGN activity and IGM heating in fossil cluster RX J1416.4+2315
H. Miraghaei, H. G. Khosroshahi, C. Sengupta +3
We study Active Galactic Nucleus (AGN) activity in the fossil galaxy cluster, RX J1416.4+2315. Radio observations were carried out using Giant Metrewave Radio Telescope (GMRT) at t…
IGM Heating in Fossil Galaxy Groups
H. Miraghaei, H. G. Khosroshahi, H. -R. Klöckner +3
We study intergalactic medium (IGM) heating in a sample of five fossil galaxy groups by using their radio properties at 610 MHz and 1.4 GHz. The power by radio jets introducing mec…
LOFAR: Recent imaging results & future prospects
George Heald, Michael R. Bell, Andreas Horneffer +27
The Low Frequency Array (LOFAR) is under construction in the Netherlands and in several surrounding European countries. In this contribution, we describe the layout and design of t…
Exact solution for the massless Cylindrically Symmetric Scalar Field in General Relativity, with Cosmological Constant
Davood Momeni, H. Miraghaei
In this article we present a new exact solution for scalar field with cosmological constant in cylindrical symmetry. Associated cosmological models is discussed. One of them descri…
Classical tests of general relativity in the Newtonian limit of Schwarzschild-de Sitter spacetime
H. Miraghaei, M. Nouri-Zonoz
Recently it has been shown that despite previous claims the cosmological constant affects light bending. In the present article we study light bending and the advance of Mercury's…
