Evolution of Virial Clouds - II: From the Formation of First Stars up to their Explosion
Noraiz Tahir, Asghar Qadir, Francesco De Paolis +1
The existence of cold gas and dust clouds close to the cosmic microwave background (CMB) temperature was proposed as a potential repository for a significant fraction of the missin…
Dark Matter Imprints on Black Hole Shadows and Chaotic Dynamics: A Comparative Study of Halo Profiles around Sgr A and M87
Ali Naqi, Mubasher Jamil, Noraiz Tahir +1
The gravitational influence of dark matter (DM) halos on the strong-field regime around supermassive black holes (SMBHs) remains largely unexplored. In the present work, we try to…
Optical Signatures of Sgr A* and M87* with Dark Matter Halos
Noraiz Tahir, Muhammad Ali Paracha, Mubasher Jamil
The event horizon telescope (EHT) has opened a new window onto the strong-field regime by imaging the shadows of the supermassive black holes (SMBHs) Sgr A* and M87*. These observa…
Black hole shadow parameters and quasi-normal modes for Weyl-incorporated gravity
Noraiz Tahir, Mubasher Jamil, Kaynat Fatima +1
An additional term of the form in the Einstein-Hilbert Lagrangian was introduced to explain the interaction between matter and pure…
The Galactic Halo Rotation by Weyl Incorporated Gravity
Asghar Qadir, Ashmal Shahid, Noraiz Tahir
A modification of the Einstein-Hilbert Lagrangian by introducing a coupling between the Weyl tensor and the stress-energy tensor was proposed to explain flat galactic rotation curv…
Dark Matter and Dark Energy in Three-Higgs Doublet Model
Mohid Farhan, Ibtehaj Hassan, Muhammad Usman +1
This article discusses the incorporation of dark matter and dark energy into a new physics model called the Three-Higgs Doublet Model. Dark matter and dark energy are accommodated…
Accounting for the absence of anomalous microwave emission in the M 31 halo
Francesco De Paolis, Faryal Naseem, Noraiz Tahir
The discovery of a temperature asymmetry in the cosmic microwave background (CMB) data towards various galaxies has opened a window for a deeper comprehension of galactic halos. A…
Messier 90 galactic halo rotation in the microwaves
F. De Paolis, V. G. Gurzadyan, A. L. Kashin +4
We used Planck data to study the Virgo Cluster's galaxy M 90 and its surroundings. We find, as in the case of certain galaxies of the Local Group and its vicinity, a substantial te…
The Baryonic Mass Estimates of the Milky Way Halo in the form of High Velocity Clouds
Noraiz Tahir, Martin Lopez Corredoira, Francesco De Paolis
The halo of our Galaxy is populated with a significant number of high-velocity clouds (HVCs) moving with a speed up to km/s. It is suggested that these HVCs might contain a n…
On the Galactic Halos Rotation by Planck Data
Noraiz Tahir, Francesco De Paolis, Asghar Qadir +1
As galactic halos are not directly visible, there are many ambiguities regarding their composition and rotational velocity. Though most of the dark matter is non-baryonic, {\it som…
Virial clouds to explain rotational asymmetry in galactic halos
Asghar Qadir, Noraiz Tahir, Francesco De Paolis +1
The rotation of the galactic objects has been seen by asymmetric Doppler shift in the CMB data. Molecular hydrogen clouds at virial temperature may contribute to the galactic halo…
The rotational kinetic Sunyaev-Zeldovich contribution to the temperature asymmetry toward the M31 halo
Noraiz Tahir, Francesco De Paolis, Asghar Qadir +1
Temperature asymmetry in the cosmic microwave background (CMB) data by the Planck satellite has been discovered and analyzed toward several nearby edge-on spiral galaxies. It provi…
Seeing the halo rotation of nearby spiral galaxies using Planck data
Noraiz Tahir, Francesco De Paolis, Asghar Qadir +1
The rotation of the galactic halos is a fascinating topic which is still waiting to be addressed. Planck data has shown the existence of a temperature asymmetry towards the halo of…
Virial clouds explaining the observed rotational asymmetry in the galactic halos
Asghar Qadir, Noraiz Tahir, Muhammad Sakhi
Rotation of galactic objects has been seen in the cosmic microwave background (CMB) that could be ascribed to molecular hydrogen clouds with, or without, dust contamination and con…
Virial clouds evolution from the last scattering upto the formation of first stars
Noraiz Tahir, Asghar Qadir, Muhammad Sakhi +1
The asymmetry in the cosmic microwave background (CMB) towards several nearby galaxies detected by Planck data is probably due to the rotation of "cold gas" clouds present in the g…
Evolution of virial clouds-I: from surface of last scattering up to the formation of population-III stars
Noraiz Tahir, Asghar Qadir, Muhammad Sakhi +1
The analysis of WMAP and Planck CMB data has shown the presence of temperature asymmetries towards the halos of several galaxies, which is probably due to the rotation of clouds pr…
Rotating baryonic dark halos
F. De Paolis, A. V. Gurzadyan, A. A. Nucita +8
Galactic halos are of great importance for our understanding of both the dark matter nature and primordial non-Gaussianity in the perturbation spectrum, a powerful discriminant of…
