About

Alexey Vikhlinin has studied astrophysics at the Space Research Institute (IKI) in Moscow under di- rection of Prof. Rashid Sunyaev in 1991-1995. He was a CfA Postdoctoral Fellow in 1996-1998, and later joined the Chandra X-ray Center (2001). In the next several years, Vikhlinin led the calibration work for Chandra’s main detector, and formulat- ed and led a large-scale project aimed at using the Chandra observations of ROSAT-detected distant galaxy clusters for cosmology. Vikhlinin co-shared the 2008 Rossi Prize for his work on galaxy clusters and cosmology. In recent years, Vikhlinin has led the NASA mission concept study for Lynx, a major X-ray astronomical facility which would feature a 1.5 orders of magnitude gain in throughput while maintaining the Chandra’s angular resolution.

Projects

ChaMP (Chandra Multiwavelength Project) and ChaMPlane (Chandra Multiwavelength Plane) Survey

High Energy Astrophysics

NASA’s Chandra X-ray Observatory is a groundbreaking space telescope, with abilities beyond anything that came before it. The Chandra Multiwavelength Project (ChaMP) and Chandra Multiwavelength Plane (ChaMPlane) Survey exploit those abilities to catalog the variety of X-ray sources within archival Chandra data, with follow-up using other telescopes in other parts of the spectrum of light. The surveys identified previously unknown galaxy clusters, quasars, neutron star binary systems, and other significant astronomical sources both in the plane of the Milky Way — ChamPLane — and beyond the galaxy — ChaMP. ChaMP and ChaMPlane are led by astronomers at the Center for Astrophysics | Harvard & Smithsonian, in collaboration with researchers at a number of other institutions in the United States and around the world.

Telescopes and Instruments

Giant Magellan Telescope

Is Earth unique, or are there other planets with life in the Milky Way? To answer this question and many others, astronomers need larger and more sensitive observatories than anything we currently have. For that reason, the Center for Astrophysics | Harvard & Smithsonian is collaborating with a number of other institutions around the world to create the Giant Magellan Telescope (GMT), currently under construction in Chile. The GMT will consist of seven large mirrors acting in concert as one giant telescope 80 feet across. That large size provides an unprecedented view of the sky and the ability to detect the chemical composition of exoplanet atmospheres. Like NASA’s Hubble Space Telescope, the GMT will be a powerful tool across the field of astronomy, providing insights into the formation of planets, the structure of galaxies, and the evolution of the universe itself.

Einstein Observatory

NASA’s Einstein Observatory was the first X-ray space telescope designed to produce images of astronomical X-ray sources. The spacecraft operated from 1978 through 1981, providing important observations of pulsars, supernova remnants, supermassive black holes in other galaxies, and many more, paving the way for NASA’s Chandra X-ray Observatory. The X-ray telescope was designed by researchers at the Center for Astrophysics | Harvard & Smithsonian.

Chandra

The Chandra X-ray Observatory is NASA’s flagship X-ray observatory, providing essential data on everything from the environment surrounding newborn stars to the emissions from hot plasma inside galaxy clusters. The Smithsonian Astrophysical Observatory (SAO), as part of the Center for Astrophysics | Harvard & Smithsonian, manages Chandra’s day-to-day operations, providing spacecraft control, observation planning, and data processing for astronomers. Chandra is one of NASA’s orbiting Great Observatories, along with the Hubble.

MMT Observatory

The MMT Observatory is the premier visible-light and infrared telescope jointly managed by the Smithsonian Astrophysical Observatory, part of the Center for Astrophysics | Harvard & Smithsonian, and the University of Arizona. Located at the Fred Lawrence Whipple Observatory (FLWO) in southern Arizona, this 6.5-meter (21 foot) telescope is used to study objects across the field of astronomy, from the Solar System to distant galaxies. The MMT has provided a testbed for new telescope technologies developed by scientists and engineers at the CfA and the University of Arizona.

Lynx X-Ray Observatory

The Lynx X-ray Observatory is a proposed X-ray space telescope, designed to be the next generation following NASA’s Chandra X-ray Observatory and the European Space Agency’s upcoming Athena Telescope. This observatory will be able to take images of a larger area of the sky in X-ray light with better resolution than any existing telescope, allowing astronomers to study the first supermassive black holes, the hot gas surrounding galaxies as they evolve, and radiation from the earliest stars. Researchers from the Center for Astrophysics | Harvard & Smithsonian and other universities are presenting Lynx to NASA for consideration in the 2020 Decadal Survey, with a proposed launch date in the mid-2030s.
