This is an example of how powerful the techniques of analysis of extragalactic
microlensing can be.
While planets are often discovered within the Milky Way using microlensing, the gravitational effect of even small objects can create high magnification leading to a signature that can be modeled and explained in extragalactic
An expert in extragalactic
astronomy, Kinney has published more than 80 papers on quasars, blazars, active galaxies and normal galaxies, and signatures of accretion disks in active galaxies.
He explains concepts like general relativity, neutron stars, and the big bang and their historical context, and the work of JapanAEs KAGRA (Kamioka Gravitational Wave Detector) , ChileAEs Atacama Cosmology Telescope, the South PoleAEs BICEP (Background Imaging of Cosmic Extragalactic
Polarization) detectors, and the USAE LIGO labs in the search.
The source, FRB 121102, was first detected in 2012 as a fast radio burst (FRB): an ultrabright, ultrabrief burst of radio waves with mysterious, likely extragalactic
origins (S&T: July 2016, p.
Although the possibility that FRBs are produced by extragalactic
civilizations is more speculative than an astrophysical origin, quantifying the requirements necessary for an artificial origin serves, at the very least, the important purpose of enabling astronomers to rule it out with future data,' the pair said in the conclusion of their study.
They were trying to decipher the extragalactic
background light, or EBL, a diffuse glow that fills the universe (SN:9/7/13, p.
The Milky Way as a whole is moving at a velocity of approximately 600 km per second with respect to extragalactic
frames of reference.
A team of astrophysicists from Notre Dame, Maryland, Berkeley and Australia have formed the "Kepler ExtraGalactic
Survey," or KEGS, specifically to apply the power of Kepler to study galaxies and supernovae.
The list of award winners of the night includes leading educationist Humaira Bachal who runs Dream Model Street School for underprivileged children; Pakistans first female taxi driver, Zahida Kazmi; Pakistans first female fire fighter Shazia Parveen; Director of Justice Project Pakistan, Sarah Bilal; young national level Squash player Sadia Gul; and the first Pakistani woman to earn a PhD in Extragalactic
Astrophysics, Dr Mariam Sultana.
At the same time, they will be greeted with visuals of the solar system and interstellar and extragalactic
space provided by the Eugene Astronomical Society.
En ese contexto, el descubrimiento hecho por los responsables del proyecto BICEP2 (Background Imaging of Cosmic Extragalactic
Polarization) representa la primera evidencia directa de la inflacion cosmica; asimismo, se lograron observar las huellas de ondas gravitacionales que, aunque no demuestran su existencia, si permiten avanzar en su busqueda.
