Why are fireworks coloured, how can we tell what elements are in stars just from the light we see? This video explains why physics is all about sunshine and rainbows.

086 - Emission and Absorption Spectra
In this video Paul Andersen explains how the photons emitted from or absorbed by an atom or nuclei is directly related to electrons moving between energy level. Absorption and emission are a direct result of the conservation of energy. Scientists may use the emission spectra of material to determine the atoms or molecules contained within the material.

The emission spectrum of a chemical element or chemical compound is the spectrum of frequencies of electromagnetic radiation emitted by the element's atoms or the compound's molecules when they are returned to a lower energy state.
Each element's emission spectrum is unique. Therefore, spectroscopy can be used to identify the elements in matter of unknown composition. Similarly, the emission spectra of molecules can be used in chemical analysis of substances.
In physics, emission is the process by which a higher energy quantum mechanical state of a particle becomes converted to a lower one through the emission of a photon, resulting in the production of light. The frequency of light emitted is a function of the energy of the transition. Since energy must be conserved, the energy difference between the two states equals the energy carried off by the photon. The energy states of the transitions can lead to emissions over a very large range of frequencies. For example, visible light is emitted by the coupling of electronic states in atoms and molecules (then the phenomenon is called fluorescence or phosphorescence). On the other hand, nuclear shell transitions can emit high energy gamma rays, while nuclear spin transitions emit low energy radio waves.

The Fanaroff-Riley Dichotomy in AGN Jets and Their Emission-line Regions by Prajval Shastri
Extragalactic Relativistic Jets: Cause and Effect PROGRAM LINK: www.icts.res.in/program/ERG2015 DATES: Monday 12 Oct, 2015 - Tuesday 20 Oct, 2015 VENUE: Ramanujan Lecture Hall, ICTS Bangalore DESCRIPTION : Active Galactic Nuclei (AGN) are the luminous centers of galaxies that are believed to be powered by accretion of matter on to supermassive black holes. Bipolar outflows or jets that are launched from the accretion-disk black hole systems carry away angular momentum and impact the surrounding matter both inside and outside the host galaxies. Given the current computational power, AGN have become a test bed for general relativistic magnetohydrodynamics. AGN are sites of coalescing supermassive black holes, which are one of the primary science drivers of gravitational wave astronomy. ... -

Local Laboratories for high-redshift astrophysics
Speaker: Alaina Henry (GSFC) Abstract: The Lyman alpha emission line is an important diagnostic tool, used widely in attempts to understand the properties of galaxies and the intergalactic medium at early cosmic times. With a relative ease of observation at z > 2-3, and the potential to constrain outflows, dust, and neutral gas in the circumgalactic and intergalactic media, Lyman Alpha surveys have grown dramatically in the last decade. However, we are still challenged to predict Lyman alpha emission (or lack thereof); consequently, our ability to interpret high-redshift results is limited. I this talk, I will review some of the key high-redshift observations, and then turn to what we can learn from low-redshift galaxies. I will discuss new results from a sample of low-redshift obj... -

Extragalactic Relativistic Jets: Cause and Effect
PROGRAM LINK: www.icts.res.in/program/ERG2015
DATES: Monday 12 Oct, 2015 - Tuesday 20 Oct, 2015
VENUE: Ramanujan Lecture Hall, ICTS Bangalore
DESCRIPTION :
Active Galactic Nuclei (AGN) are the luminous centers of galaxies that are believed to be powered by accretion of matter on to supermassive black holes. Bipolar outflows or jets that are launched from the accretion-disk black hole systems carry away angular momentum and impact the surrounding matter both inside and outside the host galaxies. Given the current computational power, AGN have become a test bed for general relativistic magnetohydrodynamics. AGN are sites of coalescing supermassive black holes, which are one of the primary science drivers of gravitational wave astronomy.
AGN jet astrophysics is at an important and exciting junction in time with the availability of ever-more sensitive multi-wavelength data and increased computing power. This program will bring leading experts working on various aspects of AGN jet physics from around the world to Bangalore. The program will prove to be an invaluable opportunity for boosting AGN studies in India in time for India's participation in upcoming mega projects like SKA, TMT, LIGO-India, and ASTROSAT.
Pedagogical lectures will be delivered on the first two days on topics related to the advanced-level talks that will take place later in the program. Talks highlighting the latest results on AGN Jets and Outflows from new observatories like the ALMA, NuSTAR, and Fermi-GST among others, will be presented on days 3-7. An evening talk by Dr. Bernard Fanaroff will take place on day 5. Tutorials on Introduction to CASA software for ALMA, EVLA, GMRT radio data-reduction, and NuSTARDAS software for NuSTAR X-ray data-reduction, will be held on the final two days of the program.
This program is organized in partnership with the Indian Institute of Astrophysics, Bangalore.

Speaker: Alaina Henry (GSFC)
Abstract:
The Lyman alpha emission line is an important diagnostic tool, used widely in attempts to understand the properties of galaxies and the intergalactic medium at early cosmic times. With a relative ease of observation at z > 2-3, and the potential to constrain outflows, dust, and neutral gas in the circumgalactic and intergalactic media, Lyman Alpha surveys have grown dramatically in the last decade. However, we are still challenged to predict Lyman alpha emission (or lack thereof); consequently, our ability to interpret high-redshift results is limited. I this talk, I will review some of the key high-redshift observations, and then turn to what we can learn from low-redshift galaxies. I will discuss new results from a sample of low-redshift objects (the z~0.2 "Green Peas") with strong line emission and low metallicity. Using UV spectroscopy from HST/COS, I will test prevailing theories of Lyman alpha escape, including resonant scattering in an outflow, and the geometry of neutral gas. In fact, the Green Pea galaxies are useful local laboratories for astrophysics beyond Lyman alpha output. Looking forward, I will discuss some of the ways that these (or similar) objects can serve as local laboratories for other astrophysics, including gas-phase abundance diagnostics.
