More information on the first eVLBI Science experiment is available in a press release (PDF).

eVLBI Science (posted 27 Sep 2004)

The first eVLBI science demonstrations took place 22 Sep 2004 with four telescopes of the EVN observing spectral line sources. The data has already been made public. More information on this latest eVLBI advance can be found at the EVN Newsletter.

eVLBI fringes to Arecibo (posted 17 Sept 2004)

On Friday 10th September, real-time fringes were detected between the 305m Arecibo radio telescope and three EVN antennas. Click here for details.

Youngest stellar corpse (posted 14 Jul 2004)

Observations with arrays of radio telescopes around the world, including antennas of the EVN, have discovered a new feature of a previously known supernova remnant (SNR). This lies at the centre of the SNR and is likely to be associated with either a black hole or a neutron star. NRAO press release.

Real-time eVLBI Press Release (posted 18 May 2004)

A Press Release regarding the recent production of the first EVN real-time image can now be downloaded.

EVN Data Access Policy (posted 17 May 2004)

An EVN Data Access Policy document is now accessible from the EVN web pages. This deals with various issues relating to the use of the EVN Data Archive and comes into force on 1 June 2004.

First real-time EVN image (posted 29 Apr 2004)

The first real-time EVN image was produced yesterday from observations carried out using three EVN telescopes (Onsala, Jodrell Bank and Westerbork). The data rate was 32Mb/s, this data being transferred from the stations directly into the EVN MkIV correlator at JIVE. The source observed was a double-image lens system, the expected structure being easily recovered in the map.

EVN Symposium and Users' Meeting

The 7th EVN Symposium and Users' Meeting will be held at Toledo, Spain on October 12-15, 2004. See also the EVN meetings page.

Transatlantic real-time fringes (posted 29 Mar 2004)

Thursday 25 March saw the detection of real-time fringes between the Westford antenna in Massachusetts (USA) and Onsala in Sweden. This is the first successful intercontinental real-time VLBI experiment. Data were acquired using Mark 5A disk-recording systems at the stations and correlated with the Mark 4 correlator at Haystack (no disk buffering was used at either that stations or the correlator).

New EVN web pages (posted 26 Mar 2004)

As you will have no doubt noticed, the EVN web pages have changed in appearance, this upgrade being prompted by the successful introduction last year of new JIVE pages. These pages have been tested on most modern browsers (Mozilla, Opera and IE) as well as Netscape 4. Please send any comments and suggestions to Andy Biggs (biggs@jive.nl).

eVLBI fringes

eVLBI fringes have been detected at JIVE from data recorded remotely from Westerbork and Jodrell. Data was streamed directly across the internet from the VLBI formatter to disk packs at JIVE and correlated within 15 minutes of the end of the experiment.

eVLBI report

A short report describing recent eVLBI results has been put together by Steve Parsley (October 2003).
