PROMPT Telescopes

PROMPT Telescopes is a astronomy topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand PROMPT Telescopes rather than just read about it. In short: PROMPT, an acronym for Panchromatic Robotic Optical Monitoring and Polarimetry Telescopes, is being built by the University of North Carolina at Chapel Hill at Cerro Tololo Inter-American Observatory (CTIO) in Chile. PROMPT's primary objective is rapid and simultaneous multiwavelength observations of gamma-ray burst afterglows, some when they are only tens of seconds old.

Key takeaways

PROMPT Telescopes belongs to astronomy; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect PROMPT Telescopes to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of PROMPT Telescopes from memory before moving on to harder problems.

Reference excerpt

PROMPT, an acronym for Panchromatic Robotic Optical Monitoring and Polarimetry Telescopes, is being built by the University of North Carolina at Chapel Hill at Cerro Tololo Inter-American Observatory (CTIO) in Chile. PROMPT's primary objective is rapid and simultaneous multiwavelength observations of gamma-ray burst afterglows, some when they are only tens of seconds old. In addition to measuring redshifts by dropout, and early-time SFDs and extinction curves of sufficiently bright afterglows in unprecedented detail, PROMPT will facilitate quick response observations at larger observatories such as the UNC-led 4.1-m SOAR Telescope. PROMPT will also serve as a platform for undergraduate and high school education throughout the State of North Carolina.

PROMPT consists of six 0.41-m Ritchey-Chrétien telescopes by RC Optical Systems on rapidly slewing (9°/sec) Paramount ME mounts by Software Bisque, each under a clamshell dome by Astro Haven. Five of these telescopes use rapid-readout (<2 sec) Alta U47+ cameras by Apogee, which make use of E2V CCDs. The sixth is being outfitted with an LN2-cooled Micro-Cam by Rockwell Scientific for NIR imaging. Each mirror and camera coating combination has been optimized for a different wavelength range, including a u-band optimized telescope. Although other filters are available, PROMPT automatically observes GRB localizations in ugriz simultaneously. The R-band telescope will additionally measure polarizations. The polarimeter was designed and built at UNC's Goodman Laboratory for Astronomical Instrumentation. PROMPT is under the control of "Skynet," a prioritized queue scheduling system that is being developed at UNC-Chapel Hill. Skynet is written in LabView and runs on a computer at UNC's Morehead Observatory. Skynet interacts with a MySQL database and commands "Terminator" programs at each telescope. Images are automatically transferred back to a 6.5 terabyte RAID 5 with tape backup at Morehead Observatory. Users can submit jobs and retrieve data from any location via a PHP-enabled web server that interacts with the MySQL database. However, GRBs receive top priority and are automatically added to the queue via a socket connection.

Worked examples

Example 1 — a first encounter with PROMPT Telescopes

Start with the simplest possible case. Write down what PROMPT Telescopes claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to PROMPT Telescopes before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about PROMPT Telescopes ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of PROMPT Telescopes

In research: PROMPT Telescopes appears in astronomy research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses PROMPT Telescopes in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: PROMPT Telescopes is common in secondary-school and first-year university syllabi. It links to neighbouring topics Optical telescopes, University of North Carolina at Chapel Hill, so understanding it makes those chapters shorter.
In everyday life: Look for PROMPT Telescopes outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
