Timeline

1962

Abraham "Avi" Loeb (אברהם (אבי) לייב; born February 26, 1962) is an Israeli-American theoretical physicist who works on astrophysics and cosmology.

Loeb was born in Beit Hanan, Israel, in 1962.

He took part in the national Talpiot program of the Israeli Defense Forces at age 18.

1979

Loeb led a team that reported tentative evidence for the birth of a black hole in the young nearby supernova SN 1979C.

1983

While in Talpiot, he obtained a BSc degree in physics and mathematics in 1983, an MSc degree in physics in 1985, and a PhD in physics in 1986, all from the Hebrew University of Jerusalem (HUJI).

From 1983 to 1988, he led the first international project supported by the U.S. Strategic Defense Initiative.

1988

Between 1988 and 1993, Loeb was a long-term member at the Institute for Advanced Study at Princeton, where he started to work in theoretical astrophysics.

1992

In 1992, Loeb and Andy Gould suggested that exoplanets could be detected through gravitational microlensing.

1993

In 1993, he moved to Harvard University as an assistant professor in the department of astronomy, and was tenured three years later.

Loeb has written eight books, including textbooks How Did the First Stars and Galaxies Form? and The First Galaxies in the Universe.

He has co-authored many papers on topics in astrophysics and cosmology, including the first stars, the epoch of reionization, the formation and evolution of massive black holes, the search for extraterrestrial life, gravitational lensing by planets, gamma-ray bursts at high redshifts, the use of the Lyman-alpha forest to measure the acceleration/deceleration of the universe in real time, the future collision between the Milky Way and Andromeda galaxies, the future state of extragalactic astronomy, astrophysical implications of black hole recoil in galaxy mergers, tidal disruption of stars, and imaging black hole silhouettes.

In 1993, he proposed the use of the C+ fine-structure line to discover galaxies at high redshifts.

2004

In addition, a pulsar was discovered around the supermassive black hole Sagittarius A*, following a prediction by Pfahl and Loeb in 2004.

2005

In 2005, he predicted, in a series of papers with his postdoc Avery Broderick, how a hot spot in orbit around a black hole would appear; their predictions were confirmed in 2018 by the GRAVITY instrument on the Very Large Telescope which observed a circular motion of the centroid of light of the black hole at the center of the Milky Way, Sagittarius A*.

2007

Loeb is the Frank B. Baird Jr. Professor of Science at Harvard University, where since 2007 he has been Director of the Institute for Theory and Computation at the Center for Astrophysics.

2008

Also, a hypervelocity star candidate from the Andromeda galaxy was discovered, as predicted by Sherwin, Loeb, and O'Leary in 2008.

Together with his postdoc James Guillochon, Loeb predicted the existence of a new population of stars moving near the speed of light throughout the universe.

Together with his postdoc John Forbes and Howard Chen of Northwestern University, Loeb made another prediction that sub-Neptune-sized exoplanets have been transformed into rocky super-Earths by the activity of Sagittarius A*.

2009

In 2009, Broderick and Loeb predicted the shadow of the black hole in the giant elliptical galaxy Messier 87, which was imaged in 2019 by the Event Horizon Telescope.

2011

He chaired the Department of Astronomy from 2011–2020, and founded the Black Hole Initiative in 2016.

Loeb is a fellow of the American Academy of Arts and Sciences, the American Physical Society, and the International Academy of Astronautics.

2013

In 2013, a report was published on the discovery of the "Einstein Planet" Kepler-76b, the first Jupiter-size exoplanet identified by detecting the relativistic beaming of its parent star, based on a technique Loeb and Gaudi proposed in 2003.

Together with Paolo Pani, Loeb showed in 2013 that primordial black holes in the range between the masses of the Moon and the Sun cannot make up dark matter.

In collaboration with Dan Maoz, Loeb demonstrated in 2013 that biomarkers, such as molecular oxygen, can be detected by the James Webb Space Telescope (JWST) in the atmosphere of Earth-mass planets in the habitable zone of white dwarfs.

In 2013, Loeb wrote about the "Habitable Epoch of the Early Universe".

In April 2021, he presented an updated summary of his ideas of life in the early universe.

2015

In 2015, he was appointed as the science theory director for the Breakthrough Initiatives of the Breakthrough Prize Foundation.

Loeb has published popular science books including Extraterrestrial: The First Sign of Intelligent Life Beyond Earth (2021) and Interstellar: The Search for Extraterrestrial Life and Our Future in the Stars (2023).

2017

In December 2017, Loeb cited ʻOumuamua's unusually elongated shape as one of the reasons the Green Bank Telescope in West Virginia should listen for radio emissions from it to see if there were any unexpected signs that it might be of artificial origin, although earlier limited observations by other radio telescopes such as the SETI Institute's Allen Telescope Array had produced no such results.

The Green Bank Telescope observed the asteroid for six hours, detecting no radio signals.

2018

In 2018, he suggested that alien space craft may be in the Solar System, using ʻOumuamua as an example.

In 2023, he claimed to have recovered material from an interstellar meteor that could be evidence of an alien starship, which some experts criticized as hasty and sensational, and for which other experts found more Earth-related explanations instead, demonstrating that the seismic signal attributed by Loeb to the alleged interstellar space craft was actually caused by ordinary truck traffic.

In 2018, he served a term as chair of the Board on Physics and Astronomy (BPA) of the National Academies.

In a series of papers with his students and postdocs, Loeb addressed how and when the first stars and black holes formed and what effects they had on the young universe.

On October 26, 2018, Loeb and his postdoctoral student Shmuel Bialy submitted a paper exploring the possibility that ʻOumuamua is an artificial thin solar sail accelerated by solar radiation pressure in an effort to help explain the object's non-gravitational acceleration.

The consensus among other astrophysicists was that the available evidence is insufficient to consider such a premise, and that a tumbling solar sail would not be able to accelerate.

In response, Loeb wrote an article detailing six anomalous properties of ʻOumuamua that make it unusual, unlike any comets or asteroids seen before.

On November 27, 2018, Loeb and Amir Siraj, a Harvard undergraduate, proposed a search for ʻOumuamua-like objects that might be trapped in the Solar System as a result of losing orbital energy through a close encounter with Jupiter.

2020

In 2020, Loeb published a paper about the possibility that life can propagate from one planet to another, followed by the opinion piece "Noah's Spaceship" about directed panspermia.

In 2024, Loeb delivered a speech in which he declared his view that the Messiah will be an alien who arrives from outer space.
