Science Highlights

Arecibo Helps Identify Magnetar at Core of “the Cow”

The Arecibo Observatory was one of 21 telescopes involved in the large-scale European Very Large Baseline Interferometry Network (EVN) radio observations of the astronomical explosion AT2018cow (“the Cow”), resulting in the detection of a magnetar - a neutron star with a very strong magnetic field.

Arecibo Observatory re-enters VLBI network with 21st-century backend:

AO, with its recently upgraded Very Long Baseline Interferometer (VLBI) backend, successfully detected fringes in concert with antennae in the European VLBI Network (EVN). The upgraded system makes the AO VLBI facility on par with other observatories in the world. Commissioning of the new system with the High-sensitivity Array is underway.

MANAGEMENT
Update

Arecibo Observatory Management Update Regarding COVID-19 Pandemic

48105d0b-2180-4447-979e-fecad4a47dc2.jpg The Arecibo Observatory’s priority is the health and safety of the staff and our users. In response to COVID-19 and in order to comply with restrictions implemented by the Government of Puerto Rico via executive order OS-2020-23, the Arecibo observatory will be implementing the following workplace changes: All AO science and science support staff will be working remotely beginning on March 16, 2020. We encourage the use of email if need to contact an AO staff member. No visitors will be allowed on the facility until further notice. If you planned on visiting the facility in the upcoming weeks, please contact us in order to discuss the details of your travel arrangement. + Read More

Update on the Status of AO Following Earthquakes in Puerto Rico

As you know Puerto Rico has been impacted with a series of significant earthquakes throughout the first weeks of 2020. All AO staff members are safe and our technical teams have completed preliminary visual analysis of the primary structure and have found no immediate damage.

"All AO staff members are safe and our technical teams have completed preliminary visual analysis of the primary structure and have found no immediate damage/ issues..." - Eng. Francisco Cordova, Director of the Arecibo Observatory

Status Update on the 430 MHz Transmitter

5d6096be-8a95-489c-86b5-2b9d39ef5c25.png Arecibo’s 430 MHz transmitter system was shut down in late 2019 following a series of long-standing issues that were exacerbated by water damage to the system during Hurricane Maria in 2017 and culminated in the loss of two klystrons due to transmitter malfunctions in 2019. The AO staff are currently working with [Diversified Technologies Inc.] (DTI) to install a new transmitter system that will include a solid-state modulator and a capacitor bank from the [Sondrestrom Upper Atmospheric Research Facility]. The expected upgrades will produce a system with higher reliability, facilitate future maintenance, and provide better protection for the klystrons, in addition to many other improvements. We will continue to share updates on the status of the new transmitter system.

S-Band Transmitter Controller Upgrades

We have begun upgrades to the planetary radar system’s S-Band transmitter controller at Arecibo. Continental Electronics Corporation recently completed a site visit and we estimate completion of the upgrades in CY2021 Q3. All of the S-band electronics will be replaced in order to extend the life and reliability of the transmitter and monitoring capabilities of the system. This will allow us to track the performance of the transmitter and klystrons individually and with higher fidelity.

Education
2d9d484b-4ce3-4b7c-b54b-5e780dfc619a.pngAN ACADEMY OF GROWTH

The STEAM Teaching at Arecibo (STAR) Academy welcomes 30 students from across the island each semester to provide them with a pre-college research experience. “It’s a head start for high schoolers because it will help them when entering college, and further, a career in research, engineering, or educating future scientists” said Anne Virkki, PI of the initiative.

The goal of the AO STAR Academy is to close the gap between demand and production within STEM careers in Puerto Rico. The fields that are covered in the program include: Planetary Sciences; Space Sciences; Computer Coding; Research Experience; and Leadership Skills, with hands-on activities.

The experience is a game-changer in the participants' life, by providing the necessary tools and experience for their future”, says Sujeily Santiago, Project Director in the Arecibo Observatory.
