NRT

New Robotic Telescope

The New Robotic Telescope (NRT) is a 4-metre class fully robotic telescope being built by the Astrophysics Research Institute at Liverpool John Moores University. It will be sited at the Observatorio del Roque de los Muchachos on the island of La Palma in the Canary Islands, alongside its predecessor the Liverpool Telescope.

The NRT is designed to be the world's largest and fastest-responding robotic telescope, capable of being on-target within 30 seconds of receiving an alert. Its primary science goal is the study of explosive and rapidly fading transient phenomena.

The NRT consists of several key engineering subsystems, each designed for optimal robotic operation and rapid response:

Optics

Ritchey-Chrétien design with segmented primary mirror

Structure

Altitude/azimuth mount for rapid slewing

Software

Autonomous robotic control system

Instruments

MOPTOP, spectrograph, and multi-band imager

Enclosure

Clamshell-style protective enclosure

Weather

Live weather station data from La Palma

The NRT uses a Phase 1 / Phase 2 proposal system:

  • Phase 1: Scientific justification and time request, submitted via this platform during open call periods. Reviewed by the NRT Telescope Allocation Committee (TAC).
  • Phase 2: Detailed observation specifications for approved proposals, including target coordinates, instrument configurations, and scheduling constraints.

To submit a proposal, register for an account or log in to the platform.

LT

Liverpool Telescope

The Liverpool Telescope (LT) is a 2.0-metre fully robotic telescope owned and operated by LJMU's Astrophysics Research Institute. Located at the Observatorio del Roque de los Muchachos on La Palma, it has been operational since 2004 and is one of the world's premier robotic telescopes.

The LT specialises in time-domain astronomy, providing rapid-response observations of transient sources including gamma-ray burst afterglows, supernovae, and variable stars.

The LT supports several proposal submission modes through this platform:

Standard (Phase 1)

Semester-based proposals submitted during open call periods. Reviewed by the relevant TAG.

Reactive Time

Fast-track proposals for urgent targets of opportunity, outside the normal semester cycle.

Z-Time

Director's discretionary time for proposals that do not fit within standard TAGs.

Ensure you select the correct TAG when submitting. For guidance, see Which TAG? on the LT website.

The Liverpool Telescope currently hosts the following instruments:

  • IO:O - Optical wide-field CCD camera (optical imaging, 10' field of view)
  • IO:I - Infrared camera (1-2.5 micron, H-band imaging)
  • SPRAT - Spectrograph for the Rapid Acquisition of Transients (low-resolution optical spectroscopy)
  • MOPTOP - Multi-colour OPTimised Optical Polarimeter (will transfer to NRT)
  • RISE - High-speed frame-transfer CCD camera for exoplanet transit timing
