The XinJiang Astronomical Observatory NSRT Pulsar Data Archive

Advances in Astronomy, 2019
The sensitivity of our pulsar observation system with typical integration time of 16 minutes has reached 0.4 mJy after we have upgraded the receiver cooling system of NanShan 25-m radio telescope (NSRT) at Xinjiang Astronomical Observatory (XAO) in 2002.

SearchCal: a virtual observatory tool for searching calibrators in optical long baseline interferometry [PDF]

Astronomy & Astrophysics, 2006
In long baseline interferometry, the raw fringe contrast must be calibrated to obtain the true visibility and then those observables that can be interpreted in terms of astrophysical parameters. The selection of suitable calibration stars is crucial for obtaining the ultimate precision of interferometric instruments like the VLTI.

J-PLUS: Discovery and characterisation of ultracool dwarfs using Virtual Observatory tools [PDF]

Astronomy & Astrophysics, 2019
Context. Ultracool dwarfs are objects with spectral types equal to or later than M7. Most of them have been discovered using wide-field imaging surveys. The Virtual Observatory has proven to be very useful for efficiently exploiting these astronomical resources. Aims.
