Slide 2

Outline About LIGO: foundation, information, individuals Provide access to LIGO PEM information by means of a straightforward interface, and give access to investigation and representation devices (e.g. DMT) utilizing those information (Make ROOT based apparatuses available by means of web)  Develop at least one model e-Labs (4 competitors, and an approach to "develop" more)  Provide a community oriented condition for members (talk gatherings, EVO  "Virtual Institute", g-Labs)  Apply lattice strategies and logic of disseminated processing to make an adaptable asset for revelation based science training . 

I. LIGO Overview L aser I nterferometer G ravitational wave O bservatory An investigation to recognize the gravitational waves (GW's) anticipated by Einstein's general hypothesis of relativity (GR). An office for galactic perception utilizing GW's - opening a radical new branch of space science! LIGO Scientific Collaboration (LSC) comprises of more than 400 researchers from more than 40 organizations No identifications yet, however maximum points of confinement set up and examination techniques created and refined. Just started year-long science run (S5) in November Skip it

LIGO Observatories LIGO Livingston Observatory (LLO) Livingston Parish, Louisiana L1 (4km) LIGO Hanford Observatory (LHO) Hanford, Washington H1 (4km) and H2 (2km)

Slide 5

Detecting Gravitational Waves Gravitational waves are time-shifting quadrupole twists of space-time: These are identified as little changes long in the arms of the Interferometers:

Slide 6

Sources of Gravitational Waves LSC researchers partake in at least one maximum farthest point/scan bunches searching for signs from: Coalescence of double frameworks: neutron stars and dark gaps (NS-NS, BH-BH, BH-NS) CHIRP! Ceaseless Wave (CW) sources, for example, turning (awry!) pulsars Bursts from supernovae (uneven!) A stochastic foundation from the early universe when all is said in done |h| = (2G/c^4) (1/r)(d^2/dt^2) Quv At double the rotational recurrence of the source

Slide 7

LIGO PEM information The essential channel from LIGO is the strain plentifulness as it changes with time: h(t) = ΔL/L Analyzing LIGO information principally includes flag handling , both in the time area and in the recurrence space. An expansive number of different channels are recorded to track instrument status and condition, including Physical Environment Monitoring (PEM) channels: Analyzing LIGO PEM information have the potential for a rich assortment of educational e-Labs.

III. Creating LIGO e-Labs What is an e-Lab? (I'm here to discover) How would you make a dynamic and advancing suite of educational and fascinating lab tests? (a case from Vassar Modern Physics Lab) Some e-Labs should be "repeatable" (and some will be "new examinations") Need in-class information taking exercises, when conceivable (material science is "physical", so make it REAL! We have a few thoughts) Need an e-Lab arrangement framework (a'la PIRA demos) Candidate LIGO e-Labs: 0) Microseism at LHO, 1) Train seismic occasions at LLO, 2) Earthquake area at LHO, 3) Tracking lightning strikes at LLO Candidate LIGO i-Lab/display Skip it

Slide 11

Example: Modern Physics Lab How would you support nonstop advancement of new and existing tests in a progressing lab course? Vassar Physics 201 - Spring 2003 - 10 understudies (5 groups) 2 weeks prep, then 5x2 week tests in "round robin", with composed reports (first & second creator exchanging)

Slide 12

Example: Modern Physics Lab How would you support ceaseless improvement of new and existing investigations in a continuous lab course? Vassar Physics 201 - Spring 2003 - 10 understudies (5 groups) – Last Experiment Added 5 "new" tests toward the finish of the semester. Last papers composed independently (and utilizing TeX) Final introduction (10 min) on a day ago to rest of class.

Slide 13

Example: Modern Physics Lab How would you manage constant advancement of new and existing tests in a progressing lab course? Vassar Physics 201 - Spring 2004 - 14 understudies (7 groups) Successful analysis and report moves the examination over to one side. New trials included sections III or IV.

Slide 14

Example: Modern Physics Lab How would you support persistent advancement of new and existing analyses in a continuous lab course? Vassar Physics 201 - Spring 2005 - 20 understudies (10 groups) – multiplied! Nonstop development of a suite of both "repeatable" beginning analyses and "new" examinations for the now arranged understudy.

Slide 15

Need "repeatable" labs Some e-Labs should be "repeatable" ventures. Regardless of the possibility that another person has effectively done them, they are new to the understudy, and they manufacture aptitudes and recognition with techniques and systems. New e-Labs will begin as "new" examinations, which originate from inquiries from existing e-Labs, or from new thoughts from researchers, educators, or understudies. My calculation: Q: "What happens on the off chance that I do this?" A. On the off chance that ( !risky ) reverberate "Try it!"

IV. Collective Tools Discussion gatherings Public and private "rooms", powerfully produced spaces for each "project" EVO  "Virtual Institute" Outlines both parts of members and a site arrange g-Labs An augmentation of the i-Labs thought to incorporate g uided e-Lab exercises Teleconferencing VRVS is muddled, however getting less demanding. iChat/AV, Net Meeting, Skype, Polycom,… Wiki information base and help gatherings Student Web Lectures at end of venture See Web Lecture Archive Project ( www.wlap.org ) and FNAL Colloquia on-line Skip it

Slide 18

Discussion Forums Starting in Summer 2004 (on-line in Feb 2005), LIGO made Einstein@Home, in light of the Berkeley Open Infrastructure for Network Computing (BOINC!), to utilize dispersed volunteer figuring to investigate LIGO information. 80,000 dynamic clients, 145,000 hosts, 77 Teraflops BOINC incorporates programming for setting up discourse discussions (message sheets). These have been valuable for troubleshooting the server and customers applications, for making declarations, for getting reports "from the field", for designers and researchers collaborating with clients, and for clients connecting with each other and building solidarity and contribution.

Slide 19

Discussion Forum Features Code for dialog gatherings could be taken straightforwardly from BOINC, with changes. (Then again utilize other famous bundles, for example, BBphp,… ) Also can be utilized for on-line logbook. Highlights: Open source code (LGPL) written in PHP with SQL database; HTML and BBcode; Localized Language bolster; Avatars; Rating framework; User profiles… Desirable changes: Private "rooms" for educator just talk, engineers just, and so on. Connections to transferred pictures (as in a logbook) or different documents. Private/Public name and Avatar. Dynamic formation of new spaces for another venture. Loft to store old.

Slide 20

Virtual Institute EVO comprises of co-PI's, counseling bunch, administration board, organization colleagues, staff, and so forth.. The Virtual Institute likewise comprises of Teachers and Students, "Project Leaders", and "Project Members", "Visitors", "Guests", and "Participants" (need to get every one of these parts and terms straight) and the "building" they all work in: For this situation the "building" is the webpage get ready for the site (gateway).

Slide 21

g-Labs The I2U2 proposition expresses that i-Labs will " begin with an engaging gallery show to find a guest's consideration… welcoming guests to proceed with their logical investigations by means of a virtutal group from their home or school." An expansion of the thought is to get intrigued learners (i-Lab members) required in a gathering movement (as a rule parts of an e-Lab) while guided by a "Team Leader" (or docent ). This is not by any stretch of the imagination another part, it's recently added accentuation to one of the expressed objectives of i-Labs.
