Dr. Robert J. Nemiroff is a Professor of Physics at Michigan Technological University. He received his Ph.D. from the University of Pennsylvania in Astronomy and Astrophysics in 1987 and his B.S. from Lehigh University in Engineering Physics in 1982.〔(【引用サイトリンク】title=RJN's Bio Page )〕 He is an active researcher with interests that include gamma-ray bursts, gravitational lensing, and cosmology, and is the cofounder and coeditor of Astronomy Picture of the Day (APOD), the home page of which receives over a million hits a day, approximately 20% of nasa.gov traffic.〔(【引用サイトリンク】url=http://www.alexa.com/siteinfo/nasa.gov )〕 He is married and has one daughter.〔(【引用サイトリンク】url=http://apod.nasa.gov/apod/lib/about_apod.html )〕 ==Research== Nemiroff's research interests include gamma-ray bursts, gravitational lensing, sky monitoring, and cosmology. Among other findings, his research on gamma-ray bursts: *showed (along with others) that gamma-ray bursts are consistent with a cosmological distance scale origin before they were discovered to be so distant〔〕 *led a team that, along with others, showed a lack of energy-dependence in the speed of photons from distant gamma-ray bursts which implies, in contrast to some theories of quantum gravity, that the universe is smooth below the Planck-length scale, as Einstein had predicted〔(【引用サイトリンク】url=http://phys.org/news/2013-01-spacetime-smoother-brew-knew.html )〕〔〕 In 1999 Nemiroff and colleague Bruce Rafert published a paper showing that continuous astronomical sky monitors could soon become a reality.〔〕 With students, Nemiroff's initial night sky monitor was an automatically repeating SLR camera with a fisheye lens deployed to Michigan Technological University in 1999, Nemiroff then led a group that designed, built, and deployed the first astronomical all sky optical web monitor, dubbed a CONtinuous CAMera (CONCAM), and in 2000 deployed it to Kitt Peak National Observatory. By the mid-2000s, most major astronomical observatories deployed CONCAM or CONCAM-like devices together capable of monitoring most of the night sky most of the time. Astronomical all sky web monitors are now common at astronomical observing sites.〔See, for example, http://www.cfht.hawaii.edu/~asiva/ & http://www.nasa.gov/connect/chat/allsky.html ; http://www.allskycam.com/〕 Subsequent collaborative efforts in astronomical deep-sky monitoring now include Pan-STARRs and LSST. In 1986, he predicted the likelihood of microlensing and calculated basic microlensing induced light curves for several possible lens-source configurations in his 1987 thesis. Among his microlensing findings, he, along with others: *predicted before observational recovery that microlensing light curves can effectively resolve the surface of source stars〔〕 *showed that microlensing boosts the brightnesses of stars actually below the magnitude limit of a survey over the survey limit〔〕 Nemiroff and graduate student Bijunath R. Patla showed that the Sun is a "very interesting gravitational lens," and Nemiroff found that GRB pulses start at the same time at every energy and that they are scale invariant over energy.〔〕 His complete publication list is (available from ADS ). 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Robert J.
