The 7-Dimensional Telescope (7DT), developed by Center for the Gravitational-Wave Universe at Seoul National University, is a multi-telescope array designed to identify the electromagnetic counterparts of gravitational-wave events. 7DT consists of twenty 50cm telescopes equipped with CMOS cameras, each providing a 1.25...

We present photometric and spectroscopic follow-up observations of the strongly-lensed H-poor superluminous supernova (SLSN) 2025wny at $z = 2.0155$. We use integral-field Keck-II/KCWI spectroscopy to obtain rest-frame ultraviolet spectra spanning $11$ to $61$ days after maximum light. We use Pan-STARRS photometry to c...

The origin of the optical emission in tidal disruption events (TDEs) remains one of the major outstanding questions in the field, in part due to the limited number of nearby events with high-cadence monitoring to track their evolving photometric and spectroscopic properties. We present multi-wavelength observations of...

Wide-field surveys now report thousands of transients per month, while spectra are obtained for only a few per cent of them. We present DETECT (DESI--Transient Event Cross-matching Tool), a pipeline that turns each Transient Name Server (TNS) alert into a distance-informed candidate within an hour by placing it in the...

Current operational tests show that Py7DT can process a typical nightly survey volume within the daily time budget while producing prompt ToO products on an approximately one-hour end-to-end timescale when the target is immediately observable.
