Samuel Gill

My name is Dr Samuel Gill and I am a Research Fellow in the Astronomy and Astrophysics group at the University of Warwick. My research is focused towards Warm Giants which bridge the gap between the Hot Jupiter population and the Solar System Giants. I am also interested in spectroscopic analysis of exoplanet host stars, low-mass eclipsing binaries, and astronomical data reduction and analysis. I am a member of the Next Generation Transit Survey consortium where I lead the single-transit working group. Our working group has published over 10 new long-period planets that were originally single-transit planet candidates from TESS, with many more in preparation.

Next Generation Transit Survey

The Next-Generation Transit Survey (NGTS; Wheatley+2018)operates an array of twelve 20cm telescopes at the ESO Paranal Observatory in Chile. Each NGTS telescope has been designed for high-precision photometry that matches TESS for all stars Tmag>12 (RMS=400 ppm in 30 min), and for stars with Tmag>9 by using multiple telescopes (RMS=100 ppm in 30 mins; see Bryant+2020). Each of the 12 NGTS telescopes has a field-of-view of 8 square degrees, providing sufficient reference stars for even the brightest TESS candidates. The telescopes observe with a custom filter between 520-890 nm and are specifically designed for precise photometry of exoplanet transits. The twelve independently mounted telescopes means that NGTS is one of the few ground-based facilities capable of monitoring multiple TESS single-transit objects simultaneously on a given night. Our photometry is stable night-to-night and is capable of identifying exoplanet transits and stellar variability from night-to-night offsets (Eva-Maria+2022).

Further details and a gallery of NGTS can be found on www.ngtransits.org, and our full publication list can be found at our NASA ADS library. You may request observations with NGTS by filling out this form, and once you submit this form, we will contact you on the email you provided in due time. If you have any questions, you can also contact us directly on ngtransits@gmail.com.

Note that publication of proprietary NGTS data is subject to the NGTS Publication Policy outlined below.

NGTS Publication Policy

Where proprietary NGTS data make a major contribution to a paper, co-authorships will be at the discretion of individual consortium members. Each individual will decide whether their contribution to the paper/project/consortium merits co-authorship on each paper when it is circulated for comments.

Where proprietary NGTS data make a minor contribution to a paper, the relevant working group lead will negotiate an appropriate number and names of NGTS co-authors, on behalf of the NGTS board (with an expected minimum of 5 co-authors). These arrangements are subject to approval by the NGTS Board, including the distinction between major and minor contributions.

All draft papers will be circulated to the full NGTS consortium for comments at least one week before submission, and preferably earlier.
