A search for planetary transits on a set of 1.4 million multi-sector DIAmante lightcurves

I report the results of a new search for transiting planets on a set of 1.4 million lightcurves extracted from TESS Full Frame Images (FFIs) using the DIAmante pipeline. The data come from the first two years of observations of TESS (Sectors 1-26) and the study is focused on a sample of FGKM dwarf and subgiant stars optimized for the search of transiting planets. The search was performed on the detrended and stitched multi-sector lightcurves applying the Box-fitting Least Squares algorithm and a Random Forest classifier. I present a catalogue of 1160 transiting planet candidates, among which 842 are novel discoveries. The median radius of the transiting bodies in the catalog is 6.8 R$_{\oplus}$. The radii range from 0.8 R$_{\oplus}$ to 27.3R$_{\oplus}$ while the orbital periods range from 0.19 days to 197.2 days with a median of 3.6 days. Each candidate is accompained by a validation report and the corresponding DIAmante lightcurve. The material is available at CDS, on the ExoFOP website and on the DIAmante portal at MAST.
