Alistair R. Walker spends much of his time researching Astrophysics, Astronomy, Galaxy, Dark energy and Milky Way. Redshift, Stars, Dark matter, Metallicity and Stellar population are subfields of Astrophysics in which his conducts study. His Redshift research integrates issues from Gravitational wave and LIGO.
His studies deal with areas such as Telescope, Sky, Supernova, Cepheid variable and Photometry as well as Galaxy. The concepts of his Dark energy study are interwoven with issues in Redshift survey, Weak gravitational lensing and Cosmic microwave background. His study looks at the relationship between Milky Way and topics such as Dwarf galaxy, which overlap with Velocity dispersion.
Astrophysics, Astronomy, Galaxy, Stars and Dark energy are his primary areas of study. His study in Globular cluster, Redshift, RR Lyrae variable, Photometry and Metallicity falls within the category of Astrophysics. His RR Lyrae variable research is multidisciplinary, relying on both Variable star, Instability strip and Dwarf spheroidal galaxy.
His research in Large Magellanic Cloud, Cepheid variable, Light curve, Photometry and Supernova are components of Astronomy. His Dark energy research includes elements of Weak gravitational lensing, Telescope, Dark matter and Sky. His Telescope study combines topics from a wide range of disciplines, such as Observatory and Remote sensing.
His primary areas of investigation include Astrophysics, Galaxy, Dark energy, Redshift and Stars. His Astronomy research extends to the thematically linked field of Astrophysics. His biological study spans a wide range of topics, including Light curve, Supernova and Sky.
His work carried out in the field of Dark energy brings together such families of science as Weak gravitational lensing, Telescope, Cosmic microwave background and Photometric redshift. His studies in Redshift integrate themes in fields like Spectral density, Spectral line, Luminosity, Quasar and Galaxy cluster. He works mostly in the field of Stars, limiting it down to topics relating to Halo and, in certain cases, Stellar mass, as a part of the same area of interest.
Alistair R. Walker mainly investigates Astrophysics, Dark energy, Galaxy, Astronomy and Redshift. His Astrophysics study focuses mostly on Large Magellanic Cloud, South Pole Telescope, Surface brightness, Light curve and Stellar mass. His biological study deals with issues like Dwarf galaxy, which deal with fields such as RR Lyrae variable, Constellation, Metallicity and Star formation.
His Dark energy study combines topics in areas such as Weak gravitational lensing, Cosmic microwave background, Dark matter and Planck. His Astronomy observatory study, which is part of a larger body of work in Astronomy, is frequently linked to Research council, European research, National laboratory and Fundamental physics, bridging the gap between disciplines. His research integrates issues of Luminosity and Galaxy cluster in his study of Redshift.
