KISHIMOTO • J Sponsors: CONICYT, NRAO, ESO, MAS TORUS 2018: The many faces of the AGN obscuration Puerto Varas, Chile 10-14 December 2018 For the past 30 years, a toroidal structure in the equatorial plane around active galactic nu- clei (AGN), the so-called dusty and molecular torus, has been considered a cornerstone of unified schemes of quasars and Seyfert galaxies. However, this picture has recently been challenged through high spatial resolution infrared observations by the discovery of polar elongated dust structures, rather than doughnut shaped distributions. Similarly, recent spatially unresolved X-ray obser- vations have provided critical new insights into the toroidal obscurer and scatterer, potentially requiring a reinterpretation of long-established concepts. The first ALMA observations, for their part, have led to contradicting interpretations: either the submm emission is indeed dominated by a rotating torus structure, or it is dominated by an outflow, which would be more compatible with the elongated dust shapes seen in the infrared. Together with a dramatic increase in computational power, these observations have triggered a renaissance in modelling of the nuclear material, with models for the first time trying to not only explain the SEDs but also the spatial distribution of the dusty and molecular material. Further observational results are expected to revolutionise this picture in the coming years through the increased spatial resolution and sensitivity of ALMA and JWST, as well as the new generation of high-resolution X-ray spectrometers such as XARM. Continuing the long tradition of international TORUS workshops, we are congregated here in Puerto Varas, Chile, to investigate the many faces of AGN obscuration. Considering the new theoretical and observational work carried out across the electromagnetic spectrum, the scientific goal of the workshop is to critically assess and challenge our current "common knowledge" and "widely accepted" torus picture. What do we really know for sure? What do we only think we know? And what is it that we do not know?

To constrain models of dark energy, a precise measurement of the Hubble constant, H0 , provides a powerful complement to observations of the cosmic microwave background. Re- cent, precise measurements of H0 have been based on the ‘extragalactic distance ladder,’ pri- marily using observations of Cepheid variables and Type Ia supernovae as standard candles. In the past, these methods have been limited by systematic errors, so independent methods of measuring H0 are of high value. Direct geometric distance measurements to circumnuclear H2 O megamasers in the Hubble flow provide a promising new method to determine H0 .The Megamaser Cosmology Project (MCP) is a systematic effort to discover suitable H2 O mega- masers and determine their distances, with the aim of measuring H0 to a few percent.

Introduction Astronomy is concerned with the detection and measurement of natural signals emitted from astrophysical sources in the Universe. During most of its long history astronomy was restricted to a very narrow kind of signals: optical radiation. After the work of James Clerk Maxwell in the 1860s, it became clear that light is a phenomenon based on electric and magnetic perturbations and that a continuum of electromagnetic radiation should exist. Between 1886 and 1889 Heinrich Hertz, a young physicist researching at Karlsruhe University, conducted a series of experiments that would prove the existence of electromagnetic waves.

  • Overview Summer Student Program
    National Radio Astronomy Observatory REU/RET Program Report: 2010 Overview Summer Student Program Twenty‐three students participated in the 2010 NRAO Summer Student program, including 20 undergraduate students supported by the National Science Foundation (NSF) Research Experiences for Undergraduates (REU) program, four graduating senior supported by the NRAO Undergraduate Summer Student program , and six graduate students supported by the NRAO Graduate Summer Student program. This was the fifty‐first year of the NRAO Summer Research Program, which has graduated more than one thousand students in its tenure. Research initiated in previous years by some students and their mentors continues, giving the program a continuing impact even for students who have departed. There were 163 applicants to the 2010 NRAO summer student program, of whom 68 (42%) were women and 14 (9%) were under‐represented minorities. The 20 REU positions were filled by 10 women (50%) and 10 men (50%). Of all the (30) summer students that were hired, 15 women (50%) and 15 men (50%), 6 (20%) were under‐represented minorities. Eight students were assigned to Socorro (5 REU), 14 to Charlottesville (10 REU), and 8 to Green Bank (5 REU).
