E-mail: [email protected] Draft version June 14, 2018 ABSTRACT 9 One cannot understand the early appearance of 10 M⊙ supermassive black holes without invoking anomalously high accretion rates or the creation of exotically massive seeds, neither of which is seen in the local Universe. Recent observations have compounded this problem by demonstrating that most, if not all, of the high-z quasars appear to be accreting at the Eddington limit. In the context of ΛCDM, the only viable alternative now appears to be the assemblage of supermassive black holes via mergers, as long as the seeds started forming at redshifts > 40, but ceased being created by z ∼ 20−30. In this paper, we show that, whereas the high-z quasars may be difficult to explain within the framework of the standard model, they can instead be interpreted much more sensibly in the context of the Rh = ct Universe. In this cosmology, 5 − 20 M⊙ seeds produced after the onset of re-ionization (at z . 15) 9 could have easily grown to M & 10 M⊙ by z & 6, merely by accreting at the standard Eddington rate.

Veisz 1,10 The observation and manipulation of electron dynamics in matter call for attosecond light pulses, routinely available from high-order harmonic generation driven by few-femtosecond lasers. However, the energy limitation of these lasers supports only weak sources and correspondingly linear attosecond studies. Here we report on an optical parametric synthesizer designed for nonlinear attosecond optics and relativistic laser-plasma physics. This synthesizer uniquely combines ultra-relativistic focused intensities of about 1020 W/cm2 with a pulse duration of sub-two carrier-wave cycles.

Physicists had noted since about 1900 that some unknown ionizing radiation had to be present near Earth’s surface, from the manner in which the leaves of an electroscope always came together, presumably as a result of a gradual discharging. By 1912, Victor Hess (1883–1964) had made several manned balloon ascents to measure the ionization of the atmosphere as a function of altitude, making the surprising discovery3 that the average ionization above ∼1.5 km increased relative to that at sea level. By demonstrating in this manner that the source of the ionizing radiation—named cosmic rays by Robert Millikan (1868–1953) in 1925—must therefore be extraterrestrial, Hess opened up the frontier of high-energy astrophysics and was eventually awarded the Nobel prize in physics in 1936.

  • This Letter of Condolences Is Addressed to Theodore's Family, on Behalf of the Community of Greek ERC Grantees. We Are Deeply
    This letter of condolences is addressed to Theodore’s family, on behalf of the community of Greek ERC grantees. We are deeply saddened to hear the passing of Theodore Papazoglou due to covid-19. Theodore was a dear friend and colleague to several of us at FORTH in Crete and a strong advocate of the Greek scientific community. To all of us, the people who were fortunate to be supported by European Research Council (ERC) funding, Theodore was the person to reach out and ask about the process or any issue related to the grant. He was always extremely responsive, helpful, efficient and supportive. For those of us working at FORTH and NCSR Demokritos, Theodore was a friend and a colleague, with whom some have shared scientific discussions and everyday concerns about their research. Even long after his departure to Belgium, Theodore was always eager to visit Greece -and FORTH in particular- and deliver presentations about the various funding schemes of the ERC. All of us benefited from those presentations. For many years, Theodore has served with all his strength and positive energy the vision of the European Research Council, representing our country with dignity. After the passing of Fotis Kafatos, with whom Theodore worked closely since the establishment of the ERC, Theodore also helped keep the memory of Fotis alive. For all the above, his death brings great sadness to the community of Greek ERC grantees. We would like to convey our sincere condolences to his family and friends. He will be sorely missed. Kind regards, Yiota Poirazi, IMBB-FORTH, Greece Iannis Talianidis, IMBB-FORTH, Greece George Chamilos, University of Crete and IMBB-FORTH, Greece George Garinis, University of Crete and IMBB-FORTH, Greece Co-signed by: Vassilis Amiridis, National Observatory of Athens, Greece Thomas Anthopoulos, KAUST and Imperial College London Stylianos E.

  • Frontiers in Optics (Fio) 2012/ Laser Science (LS) XXVIII 14-18 October 2012
    Frontiers in Optics (FiO) 2012/ Laser Science (LS) XXVIII 14-18 October 2012 OSA’s Annual Meeting, Frontiers in Optics 2012, wrapped up today Rochester, N.Y., featuring nearly 900 presentations over five days -- 96 years after the Optical Society was founded in this very city. Collocated with the American Physical Society Division of Laser Science’s annual meeting, Laser Science XXVIII, FiO brought together more than 1,700 attendees–a significant increase over last year– covering the latest advances in all areas of optics and photonics – from adaptive optics and optical sensing to silicon photonics and quantum information science. The first day of the conference featured a variety of short courses on timely optics topics, as well as a tribute to Emil Wolf—a well-known optics luminary whose work at the University of Rochester and elsewhere has had a considerable impact on the optics community today. The second day kicked off with a Plenary Session and Awards Ceremony, showcasing presentations from five world-renowned researchers in optics and beyond. OSA’s Frederic Ives Medal Winner Marlan Scully discussed quantum photocells, followed by APS’s Schawlow Award Winner Michael Fayer of Stanford, who covered ultrafast 2D IR vibrational echo spectroscopy. Attendees were then treated to a special guest keynote presentation by Al Goshaw, a Duke University researcher who worked directly on the likely discovery of the Higgs boson particle that rocked the physics world this summer. Rounding out the session were David Williams of the University of Rochester and Paul Corkum of Canada’s NRC and University of Ottawa, who discussed retinal imaging and attosecond photonics, respectively.

  • Eleftherios Goulielmakis
    7th December 2011 - 14:15 FLASH HALL (28c) - Seminar Room Eleftherios Goulielmakis Max Planck Institute of Quantum Optics, Garching, Germany Sub-optical-cycle light field synthesis: Triggering & clocking the motion of electronics I will discuss recent progress in lightwave technologies [1-4] with focus on the synthesis of sub-optical-cycle light transients [5] and their applications in attosecond science and spectroscopy. With novel types of light-field synthesizers, operating over a spectral bandwidth of more than 1.5 octaves spanning the Near IR, visible and ultraviolet part of the electromagnetic spectrum, we are able to synthesize isolated sub-optical cycle pulses (~ 2 fs duration) to characterize their fields utilizing attosecond streaking [1], and to craft their field shapes on demand. To demonstrate the potential of new technologies for advancing attosecond spectroscopy and control, we exploit such light transients to ionize krypton atoms within a single intense field crest [5]. We probe both ionization as well as the ensuing dynamics in the generated ions by attosecond absorption spectroscopy [6]. We demonstrate, for the first time, an “all-optical” sub-femtosecond trigger of electronic processes which, when combined with EUV attosecond pulses [1], opens the door to attosecond pump - attosecond probe experiments in atoms, molecules and condensed matter. Owing to the sub-fs confinement of ionization, we have successfully triggered highly coherent electron motion in the valence shell of generated ions [7] and have been able to clock this motion with unprecedented accuracy.
