Jan Oort should also be counted in this illustrious company. Oort is certainly among the most influential astronomers of the present century, and Leiden University is proud of having had so eminent a scientist in its midst. Of course a great part of Oort's significance extended well beyond the world of the University: his personal scientific research made him a leading figure in international astronomy, as did his organizational efforts on behalf of Dutch, European, worldwide astronomy. But he also contributed to University affairs, as Director of Leiden Observatory, as a member of the University Senate, and as Dean of the Science Faculty. He was actively involved in the organisation and evaluation of University teaching, and effectively concerned with furthering the physical sciences, at a time at which it seemed that the Netherlands were falling behind in training scientists in sufficient numbers to keep up with modern worldwide developments. He was a strong supporter of the ideal of the Civitas, the academic community of all students and staff that people strove to achieve after the second World War. This ideal led Oort to devote substantial amounts of time to the Leiden Academic Arts Center, as chairman of the section for pictorial arts. A classical university has an obvious dual responsibility: to create new knowledge and to convey knowledge to its students. But it also has an obligation to preserve knowledge. When after Oort's death a great deal of new material became available (augmenting that which had previously been inventoried with support from the Netherlands Organization for Scientific Research), Leiden University therefore decided to support the description and archiving of an encompassing collection of papers, letters, and other material describing the legacy of J.H. Oort. Through the efforts of Dr. Katgert-Merkelijn, the Leiden University Library now safely harbours in its Department of Western Manuscripts a remarkably complete collection of the papers and letters of a remarkably complete member of the University community, and, of course, of the international community of astronomers. On behalf of the board of Leiden University I am pleased to introduce the volume now lying before you.

In fact, it could be argued that WWII inventions marked the inception of the modern technological era1.

Jansky (c. 1933) Around 1930, there was increasing interest in the use of radio frequencies for communication. One of the main players, the Bell Telephone Laboratories in New Jersey, asked their research engineer, Karl Jansky (Figure 1), to investigate the inter- ference environment in the “short-wave” band around 20 MHz.

(Clemens, Sanders, Scoville 1988) 21 March 2013 Astronomy 142, Spring 2013 1 Stellar encounters: relaxation time of a stellar cluster In order to behave like a gas, as we assumed last time, stars have to collide elastically enough times for their random kinetic energy to be shared in a thermal fashion. But stellar encounters, even distant ones, are rare on human time scales. How long does it take a cluster of stars to thermalize? One characteristic time: the time between stellar elastic encounters, called the relaxation time. If a gravitationally bound cluster is a lot older than its relaxation time, then the stars will be describable as a gas (the star system has temperature, pressure, etc.). 21 March 2013 Astronomy 142, Spring 2013 2 Stellar encounters: relaxation time of a stellar cluster (continued) Suppose a star has a gravitational “sphere of influence” with radius r (>>R, the radius of the star), and moves at speed v between encounters, with its sphere of influence sweeping out a cylinder as it does: v V= π r2 vt r vt If the number density of stars (stars per unit volume) is n, then there will be exactly one star in the cylinder if 2 1 nV= nπ r vtcc =⇒=1 t Relaxation time nrvπ 2 21 March 2013 Astronomy 142, Spring 2013 3 Stellar encounters: relaxation time of a stellar cluster (continued) What is the appropriate radius, r?

  • In-Class Worksheet on the Galaxy
    Ay 20 / Fall Term 2014-2015 Hillenbrand In-Class Worksheet on The Galaxy Today is another collaborative learning day. As earlier in the term when working on blackbody radiation, divide yourselves into groups of 2-3 people. Then find a broad space at the white boards around the room. Work through the logic of the following two topics. Oort Constants. From the vantage point of the Sun within the plane of the Galaxy, we have managed to infer its structure by observing line-of-sight velocities as a function of galactic longitude. Let’s see why this works by considering basic geometry and observables. • Begin by drawing a picture. Consider the Sun at a distance Ro from the center of the Galaxy (a.k.a. the GC) on a circular orbit with velocity θ(Ro) = θo. Draw several concentric circles interior to the Sun’s orbit that represent the circular orbits of other stars or gas. Now consider some line of sight at a longitude l from the direction of the GC, that intersects one of your concentric circles at only one point. The circular velocity of an object on that (also circular) orbit at galactocentric distance R is θ(R); the direction of θ(R) forms an angle α with respect to the line of sight. You should also label the components of θ(R): they are vr along the line-of-sight, and vt tangential to the line-of-sight. If you need some assistance, Figure 18.14 of C/O shows the desired result. What we are aiming to do is derive formulae for vr and vt, which in principle are measureable, as a function of the distance d from us, the galactic longitude l, and some constants.

  • Radio Astronomy
    Theme 8: Beyond the Visible I: radio astronomy Until the turn of the 17th century, astronomical observations relied on the naked eye. For 250 years after this, although astronomical instrumentation made great strides, the radiation being detected was still essentially confined to visible light (Herschel discovered infrared radiation in 1800, and the advent of photography opened up the near ultraviolet, but these had little practical significance). This changed dramatically in the mid-20th century with the advent of radio astronomy. 8.1 Early work: Jansky and Reber The atmosphere is transparent to visible light, but opaque to many other wavelengths. The only other clear “window” of transparency lies in the radio region, between 1 mm and 30 m wavelength. One might expect that the astronomical community would deliberately plan to explore this region, but in fact radio astronomy was born almost accidentally, with little if any involvement of professional astronomers. Karl Jansky (1905−50) was a radio engineer at Bell Telephone. In 1932, while studying the cause of interference on the transatlantic radio-telephone link, he discovered that part of the interference had a periodicity of one sidereal day (23h 56m), and must therefore be coming from an extraterrestrial source. By considering the time at which the interference occurred, Jansky identified the source as the Milky Way. This interesting finding was completely ignored by professional astronomers, and was followed up only by the radio engineer and amateur astronomer Grote Reber (1911−2002). Reber built a modern-looking paraboloid antenna and constructed maps of the radio sky, which also failed to attract significant professional attention.

  • Kinematic and Emission Analysis of the Relativistic Jet in the Blazar B1551+130 Using VLBI Data
    Kinematic and Emission Analysis of the Relativistic Jet in the Blazar B1551+130 using VLBI Data Shaun Julian Nicol MSci Project Imperial College London Host Institute: Supervisor: Universitat de Val`encia Prof. Eduardo Ros Ibarra June 2012 Abstract Very Long Baseline Interferometry (VLBI) allows the most energetic structures in our universe to be observed with sub-milliarcsecond resolution (parsecs at cosmological distances). These methods are particularly effective in observing the relativistic jets extending from the black hole region of active galactic nu- clei (AGN). Six epochs of VLBI data from the MOJAVE 2 cm survey taken between June 2009 and April 2012 are used to carry out the kinematic analysis of the relativistic jet in the flat spectrum radio quasar B1551+130 with red- shift z = 1:308. The apparent velocities of areas of enhanced radio emission, or `knots', in the jet, calculated through the model fitting technique, are pre- sented along with images of the source obtained through the hybrid mapping process. Superluminal velocities for the `knots' are observed with the highest apparent velocity being 10.21.8c. From this maximum velocity, the viewing angle of 5.6◦ 1◦ is derived, agreeing with the classification of the source as a FSRQ. An estimate of the luminosity Doppler boosting factor gives a value of order 102. Two jet features are observed with negative superluminal velocities, the most significant being the region closest to the base or `core' of the jet ob- served with a velocity of {10.62.7c. The flux of this region undergoes a large increase during the most recent observations, between mid 2011 and mid 2012.

  • Galactic Rotation in Gaia DR1
    Mon. Not. R. Astron. Soc. 000,1{6 (2017) Printed 10 February 2017 (MN LATEX style file v2.2) Galactic rotation in Gaia DR1 Jo Bovy? Department ofy Astronomy and Astrophysics, University of Toronto, 50 St. George Street, Toronto, ON M5S 3H4, Canada and Center for Computational Astrophysics, Flatiron Institute, 162 5th Ave, New York, NY 10010, USA 30 January 2017 ABSTRACT The spatial variations of the velocity field of local stars provide direct evidence of Galactic differential rotation. The local divergence, shear, and vorticity of the velocity field—the traditional Oort constants|can be measured based purely on astrometric measurements and in particular depend linearly on proper motion and parallax. I use data for 304,267 main-sequence stars from the Gaia DR1 Tycho-Gaia Astrometric Solution to perform a local, precise measurement of the Oort constants at a typical heliocentric distance of 230 pc. The pattern of proper motions for these stars clearly displays the expected effects from differential rotation. I measure the Oort constants to be: A = 15:3 0:4 km s−1 kpc−1, B = 11:9 0:4 km s−1 kpc−1, C = 3:2 0:4 km s−1 kpc−1 ±and K = 3:3 0:6 km s−−1 kpc−1±, with no color trend over− a wide± range of stellar populations.− These± first confident measurements of C and K clearly demonstrate the importance of non-axisymmetry for the velocity field of local stars and they provide strong constraints on non-axisymmetric models of the Milky Way.

Introduction An important window to the Universe was opened in 1933 when Karl Jansky discovered serendipitously at the Bell Telephone Laboratories that radio waves were being emitted towards the direction of our Galaxy [1]. Jansky could not pursue investigations concerning this discovery, as the Lab- oratory was devoted to work primarily in the field of communications. This discovery was also not followed by any astronomical institute, although a few astronomers did make proposals. However, a young electronics engi- neer, Grote Reber, after reading Jansky’s papers, decided to build an inno- vative parabolic dish of 30 ft. diameter in his backyard in 1935 and made the first radio map of the Galaxy in 1940 [2]. The rapid developments of radars during World War II led to the dis- covery of radio waves from the Sun by Hey in 1942 at metre wavelengths in UK and independently by Southworth in 1942 at cm wavelengths in USA. Due to the secrecy of the radar equipment during the War, those re- sults were published by Southworth only in 1945 [3] and by Hey in 1946 [4]. Reber reported detection of radio waves from the Sun in 1944 [5]. These results were noted by several groups soon after the War and led to intensive developments in the new field of radio astronomy.

Received 2008 February 27; in original form 2007 October 30 ABSTRACT A new method to measure the epicycle frequency κ in the Galactic disc is presented. We make use of the large data base on open clusters completed by our group to derive the observed velocity vector (amplitude and direction) of the clusters in the Galactic plane. In the epicycle approximation, this velocity is equal to the circular velocity given by the rotation curve, plus a residual or perturbation velocity, of which the direction rotates as a function of time with the frequency κ. Due to the non-random direction of the perturbation velocity at the birth time of the clusters, a plot of the present-day direction angle of this velocity as a function of the age of the clusters reveals systematic trends from which the epicycle frequency can be obtained. Our analysis considers that the Galactic potential is mainly axis-symmetric, or in other words, that the effect of the spiral arms on the Galactic orbits is small; in this sense, our results do not depend on any specific model of the spiral structure.
