Abstract : Launched in 2013, #RADatHomeIndia the first Indian citizen science research (CSR) in astronomy ( ). As a nationwide Inter-University CSR-collaboratory our developments are socio-scientific and discoveries are extragalactic. During the pandemic, we co-organised the first Discovery e-Camp with Nehru Planetarium (Delhi) and multiple e-workshops with DST-Rajasthan, IIT-Mandi (w/ IAU-OAD), Thapar Institute-Patiala. As an invited-talk we presented our Collaboratory model in the 3rd Shaw-International Astronomical Union (IAU) meeting and discussed the field with CSR-authorities from the NASA, Zooniverse, Galaxy Cruise and CosmoQuest (see ). Some of our discoveries were also presented at international conferences #VLAat40 #SKASciCon21 & #SALFVIII. These discoveries have been achieved through direct public participation and collaboration with ~30 institutes like ICTS-TIFR, IoP, HRI, IISERs, IITs, IISc, NISER, UM-DAE CEBS, Vigyan Prasar. Nearly 2350 citizens are learning UV, Optical, IR and radio image analysis of galaxies using RAD@home-RGB-maker web-tool participating in an online group of 4700 members. Averaged over a year, they post ~3 RGB-images and ~16 image/text comments, per day. Their preliminary discoveries are followed up with the GMRT through the GTAC-approved GOOD-RAC project. Discovery contributions that will be reported in ASI-2022, with/without GOOD-RAC results, include Speca-like spiral-host radio galaxies, new giant and episodic radio galaxies, never-seen-before relic evidence of AGN-feedback as new ~100 kpc size radio bubble, large radio filaments, and ~60 kpc size one-sided radio jet interacting with the stellar shell in two merging galaxies. As the collaboratory primarily aims at detecting faint fuzzy relic emission as “smoking gun” evidence of AGN-feedback in multi-telescope heterogeneous data, such discoveries are not only difficult for automated AI/ML based approaches but the process also has huge implication for achieving sustainable development goals and human resource development for future mega-science projects like SKA and TMT.
