cds-question@unistra.fractive-galactic-nucleiblack-holesaccretionx-ray-sourcesTidal disruption events (TDEs) have been proposed as valuable laboratories for studying dormant black holes. However, progress in this field has been hampered by the limited number of observed events. In this work, we present TDECat, a comprehensive catalogue of 134 confirmed TDEs (131 optical TDEs and 3 jetted TDEs) discovered up to the end of 2024, accompanied by multi-wavelength photometry (X-ray, ultraviolet (UV), optical, and infrared) and publicly available spectra. We also study the statistical properties, spectral classifications, and multi-band variability of these events. Using a Bayesian Blocks algorithm, we determine the duration, rise time (t_rise_), decay time (t_decay_), and their ratio for 103 flares in our sample. We find that these timescales follow a log-normal distribution. Furthermore, our spectral analysis shows that most optical TDEs belong to the TDE-H+He class, followed by the TDE-H, TDE-He, and TDE-featureless classes, which is consistent with expectations from main sequence star disruption. Using archival observations, we identify three new potentially repeating TDEs, namely AT 2024pvu, AT 2022exr, and AT 2021uvz, increasing the number of known repeating events. In both newly identified and previously known cases, the secondary flares exhibit a similar shape to the primary. We also examine the infrared and X-ray emission from the TDEs in our catalogue, and find that 14 out of the 18 infrared events have associated X-ray emission, strongly suggesting a potential correlation. Finally, we find that for three subsamples (repeating flares, infrared-emitting events, and X-ray-emitting events), the spectral classes are unlikely to be randomly distributed, suggesting a connection between spectral characteristics and multi-wavelength emission. TDEcat enables large-scale population studies across wavelengths and spectral classes, providing essential tools for navigating the data-rich era of upcoming surveys such as the Legacy Survey of Space and Time.2026A&A...707A.171Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/707/A171CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-tohttps://github.com/dlangis/TDECat : TDECathttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/707/A171https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/707/A171http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/707/A171https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/707/A171https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/707/A171http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/707/A171GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/707/A171/tdecat (TDECat: optical Tidal Disruption Event CATalogue)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/707/A171/tdecat?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/707/A171/tdecat?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/707/A171/tdecat?GETtext/xml+votable180.050000true169.7300166719.742547220.005555555555555556Cone search capability for table J/A+A/707/A171/table1 (TDE candidates sample)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/707/A171/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/707/A171/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/707/A171/table1?GETtext/xml+votable180.050000true16.837-64.272416670.0055555555555555566/26 1698 2788 2867 3905 4075 4222 4425 4549 4707 4725 4802 4812 5207 5256 5327 5409 5557 5744 5842 6195 6269 6332 6531 6599 6717 6756 6762 7029 7255 7409 7883 8137 8319 8415 8479 8589 8659 8679 8870 8970 9029 9077 9120 9139 9251 9308 9322 9337 9342 10152 10158 10166 10239-10240 10439 10563 10735 10763 10992 11035 11054 11092 11314 11343 11351 11380 11425 11438 12059 12336 12517 12523 12738 13130 13703 13720 14937 15044 15144 15236 16712 16874 17156 17334 17338 17631 17816 18260 18634 18750 18983 19449 19597 19630 19839 19936 20091 20303 20341 21096 21103 22015 22628 23178 23824 23934 26188 26396 26480 26509 27184 27220 27251 27344 27379 27610 27965 28041 28189 28225 28242 28266 28318 28405 28569 28634 31156 31362 31466 32351 32354 32477 32504 32510 32602 32684 32697 32726 33346 33460 34099 34614 36128 36404 36778 36930 37531 41423 43818 44211 44339 45537 46474 48111 48271 48541 48702https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/707/A171?format=asciiX-raydefaultJ/A+A/707/A171/tdecatTDECat: optical Tidal Disruption Event CATaloguerecnoRecord number assigned by the VizieR team.
