Research Institute
Introduction
 Pisgah Astronomical
Research Institute (PARI) is
 A public not-for-profit public
foundation
 dedicated to providing
research and educational
access to radio and optical
astronomy for a broad crosssection of users

PARI has the infrastructure and
building space available for:
 Astronomers, Physicists,
Engineers, Post-Docs, Graduate
Students
 Use as a base for science and
environmental education and
studies.
 Astronomical Observations
 Technology Research &
Development
 Student Research Projects
History and Location


PARI is located on 200 acres
in the Pisgah Forest near
Asheville, NC
The site is relatively free of
light and radio
interference.
* PARI

NASA began building the
facility in 1962 for Gemini
and Apollo space mission
communications.

In a bowl shaped valley
that serves to shield the
antennas within. The
remote location and 3100
feet elevation also
enhances the sky
darkness for optical
astronomy.

It is now the home of
PARI.

26m Radio Telescopes
26 Meter Radio Telescopes
The PARI campus has
two 26-m (85 ft.) radio
telescopes that have
recently been modified
for precise pointing and
sidereal tracking. Each
telescope has a suite of
feeds and receivers.
26 East
These telescopes can be
controlled together as an
interferometer or
operated separately from
the master control
center.
26 West

327 MHz pulsar feed

1420 MHz hydrogen

4.8GHz formaldehyde

6.7GHz methanol

Dual 15hp motors per
axis for sidereal
tracking and improved
efficiency.


Radome is a pseudo random
pattern to reduce the dome’s
structure effects of the
antenna pattern

Precision 0.4mm antenna
surface supports operations
to 60 GHz.

This radio telescope may
become the Microwave
Astrophysics for Science
Education Research (MASER)
Observatory designed to
survey the Galactic Plane for
water masers occurring in
regions of star formation.

20 MHz Receiver
To study the powerful radio
emission variations as a function of
frequency, R. Flagg, and Jim Sky
(Radio Sky Publishing) have
designed hardware to work with a
pair of M-Squared 17-30LP7 log
periodic yagis to be used between
17 and 30 MHz.
Solar energy bursts are being
measured during the day using this
antenna facility.

Optical Astronomy

A 44 inch mirror will serve as an
addition for our optical research
facilities. Funding is being
actively sought to complete
construction of this telescope.

Several 20cm to 50cm
optical telescopes are
involved in variable star
and gamma ray burst
optical counterpart
research.
PARI Optical Ridge
• Location: Optical observatories
are 500 m from the PARI Main
Campus and runs East-West
with sharp N-S drop-offs
• Altitude 910 m, Latitude 35O
11.8’ N, Longitude 82O 52.3’ W
• Horizon: Lowest point is 0.25O
and highest point is 5O
• Skies: Average of two nights
per week for spectroscopy,
differential photometry,
astrometry
• Ideal for long-term and survey
work

These are roll-off roof observatories. The one on the left
(North) is used for gamma ray burst observations and the
other (South) is used for variable star observations.

PARI has entered into a partnership with the University of North
Carolina 16 campus system to form the Pisgah Astronomical
Science Research, and Education Center (PARSEC).
The goals of PARSEC are to:
  Strengthen the existing bond with the UNC system;
  Foster new opportunities for research and education within
the system;
  Ensure the future availability of PARI’s resources regionally,
nationally, and for the University of North Carolina system.
