We've rescheduled the hack day to accommodate for the fact that many people are still returning from vacation. It will now be Thursday, Jan 14 from 11 am - 4 pm in Marlar Lounge 37-252.
This is the perfect time to work on a small project that you've been meaning to get to, or to learn new coding tools and tricks!
Nothing says "hacking" like throwing together a last minute group coding session! Inspired by the American Astronomical Society (AAS) Hack Day, taking place as part of their annual winter meeting, Code Coffee will host a hack day at the MIT Kavli Institute for Astrophysics and Space Research. What is a hack day, you ask? It's about getting together to write code or work on some other project, *fast*. It could be for science or just for fun! You don't need to bring an idea to participate, and a range of expertise is appreciated (be it C++, python, php, or web design). So grab a friend and come to Marlar for some snacks and coding!
Maximum: 40 people
To attend, please sign up (by 3pm Jan 13) using the Google form

Determination of high precision abundances is an important goal of all spectroscopic studies. Accurate modelling of stellar spectra is therefore essential to determine these abundances and stellar parameters. I will explain in this talk the non-Local Thermodynamic Equilibrium (non-LTE) approach to modelling stellar spectra of cool stars, highlighting the important role that Hydrogen collisions play.

In the summer of 1999, NASA launched the third of its great observatories--the Chandra X-ray telescope. Like the Hubble Space telescope which preceded it, Chandra is designed to have an unprecedented ability to create images and spectra of astrophysical objects, except working with high energy X-rays instead of optical light. This means that Chandra views some of the universe's most exotic and energetic phenomena: supernovae, neutron stars, black holes, jets traveling at nearly the speed of light emanating from near the center of clusters of galaxies. In this talk, we'll take a tour of the discoveries made by the Chandra X-ray telescope, starting with studies of our own solar system, moving outward to nearby stars, to the center of our own Galaxy where a black hole 40 millions times the mass of our Sun lurks, to distant clusters of Galaxies where the most massive black holes, billions of times the mass of our Sun, reside.
Two tours will follow this talk. See separate listing for each tour and visit the MKI website for complete details.

According to Einstein's theory, gravity produces what is, in effect, an index of refraction. Light passing in the vicinity of an astronomical object will be delayed, deflected and distorted by the variations in this index of refraction, in a manner exactly analogous to terrestrial mirages. Such cosmic mirages are a major tool for the study of dark matter in galaxies and clusters of galaxies.

The Space Nanotechnology Laboratory (SNL) develops advanced lithography and nano-fabrication technology for high performance space instrumentation, as well as nanometer-accuracy metrology and assembly technology. Two current efforts are the development of nanofabricated soft x-ray gratings, the so-called critical-angle transmission (CAT) gratings, and the development of high-precision focusing X-ray mirrors. CAT gratings require the fabrication of sub-micron structures with extreme geometries and sub-nanometer precision, while x-ray mirrors are formed at 600 deg C while floating on porous air bearings and shaped further using ion implantation. These efforts are aimed at instruments that can help find the missing baryons in the Cosmic Web and reveal the secrets of dark matter.
PLEASE NOTE: There will be a tour of the Space Nanotechnology Laboratory (SNL) from 3:15-4:15pm. The pre-requisite for going on the SNL tour is attending this talk. The tour is limited to SIX people; advance sign-up required starting at 2:25 pm in 37-252. You must attend this talk to take the tour.

A critical chapter in the Universe’s history, known as the Dark Ages, remains nearly entirely unobserved. During this time period, our universe underwent a dramatic transformation from a relatively uniform mixture of hydrogen, helium, and dark matter filaments, into the luminescent and chemically complex realm of stars and galaxies that we live in today. The time period over which the first luminous sources turned on is known as the cosmic dawn.
In this talk, I will discuss how the observational technique known as 21cm tomography which will allow us to observe the dark ages and the cosmic dawn, allowing for us to learn about the formation and evolution of the first galaxies.

Advanced LIGO is on the cusp of using gravitational waves as a tool for observing the universe. What are gravitational waves, and how do we use them to observe the universe? I will describe how gravitational waves are produced by violent and interesting astronomical events, and why they are especially useful for teaching us about those events. I will emphasize that these waves are analogous to sound, and will illustrate how we learn from them with some examples of what theory tells us certain interesting example gravitational waves “sound like” to the “ears” of a detector like LIGO.
Please note: two related activities will follow Professor Hughes' presentation.

NASA's Neutron star Interior Composition ExploreR ("NICER"), will be launched to the International Space Station in August 2016. The NICER detector team at the MIT Kavli Institute for Astrophysics has delivered Si drift detectors and signal processing electronics for the 56 cameras that constitute the Instrument. The cameras are sensitive to X-ray photons in the range 0.2-12 keV, and each event will be time-tagged with an instrument clock that ticks at 40 ns. This talk will review the science goals, the instrument technology, and the calibration equipment that allows us to accomplish requirements, including the achievement of timing accuracy to 100 ns in the Solar System barycenter.

Black holes are perhaps the most mind-boggling objects ever conceived by physicists and there is hardly any science fiction series today that will not feature them in some capacity. However, black holes are also very much observable and one of the major topics of today's X-ray astronomy.
In this talk I will give a very short overview of what black holes are, where we find astrophysical black holes, why we need X-ray astronomy and thus satellite-based telescopes such as Chandra to observe black holes, and how observations of both, supermassive black holes in the centers of galaxies and the "small" black holes of only a few solar masses in binary star systems, improve our understanding of the physics of our universe.

Einstein's theory of general relativity predicts the existence of gravitational radiation. Since gravity is a weak force, it takes extreme masses and energies to produce a detectable gravitational wave signature. Indirect evidence for the existence of this radiation has been collected using pulsar measurements. The Laser Interferometer Gravitational-Wave Observatory (LIGO) is an experiment designed to directly detect this radiation, and use it to study exotic astrophysical phenomena. To do this, LIGO must measure length changes with a precision of 10-19 meters, less than a thousandth of a proton diameter. In this talk, I will briefly discuss gravitational radiation and its sources, and I will also describe the LIGO detectors and the physics involved in their operation. Finally, I will discuss some of the quantum limits on making this type of precision measurement, and the ways in which LIGO hopes to beat these limits.
No enrollment limit, no advance sign up for this talk.
Please Note: A tour of the Laser Interferometer Gravitational Wave Observatory (LIGO) Lab will follow this talk. To take the tour (2:45-4:00pm), you must register for the tour and attend both talks preceding the tour.

The stellar binary SS 433 was once featured on Saturday Night Live as the "comin' and a-goin' star". By means that are still somewhat mysterious, the system ejects blobs of plasma in opposite directions at a speed of about a quarter of the speed of light. The compact object that is responsible for providing the impetus for this plasma is probably a black hole about 10 times the mass of the Sun. I show what we've come to understand about the system and its jets such as how their directions trace out twin cones on the sky. X-ray spectroscopy, using the Chandra High Energy Transmission Grating Spectrometer that were built here at MIT, shows that the plasma temperature reaches at least 100 billion degrees and can be used to measure the density and location of the outflows we call jets.
