Isoperimetric surfaces and area-angular momentum inequality in a rotating black hole in New Massive Gravity
Andrés Aceña, Ericson López, Mario Llerena
We study the existence and stability of isoperimetric surfaces in a family of rotating black holes in New Massive Gravity. We show that the stability of such surfaces is determined…
The HI Distribution Observed toward a Halo Region of the Milky Way
Ericson López, Jairo Armijos, Mario Llerena +1
We use observations of the neutral atomic hydrogen (HI) 21-cm emission line to study the spatial distribution of the HI gas in a 8090 region of the Galaxy…
Upper Limits to Magnetic Fields in the Outskirts of Galaxies
Ericson López, Jairo Armijos-Abendaño, Mario Llerena +1
Based on CO(2-1) public data, we study the monoxide oxygen gas excitation conditions and the magnetic field strength of four spiral galaxies. For the galaxy outskirts, we found kin…
Dust Deficiency in the Interacting Galaxy NGC 3077
Jairo Armijos-Abendaño, Ericson López, Mario Llerena +2
Using 70 m observations taken with the PACS instrument of the Herschel space telescope, the dust content of the nearby and interacting spiral galaxy NGC 3077 has been compared…
An Extreme Rotating Black Hole in New Massive Gravity Theory
Andrés Aceña, Ericson López, Mario Llerena
New Massive Gravity is an alternative theory to General Relativity that is used to describe the gravitational field in a (2+1)-dimensional spacetime. Black hole solutions have been…
Cosmological Redshift in a Bianchi I Axisymmetric Model: A Qualitative Analysis
Ericsson López, Mario Llerena
Cosmic Microwave Background anomalies suggest that the Universe is slightly anisotropic, so a Cosmological Model that does not satisfy the Cosmological Principle is necessary. Anis…
