<div>Current transient research is heavily biased towards optical discovery, with widefield surveys such as ZTF, Pan-STARRS and ATLAS scouring the sky for transients on a nightly basis. As a consequence, transient events that are affected by (heavy) dust exctinction
are often missed, or not classified. For example, tidal disruption events (TDE) are disproportionally discovered in post-starburst galaxies with little to no dust content, suggesting a preference for such an environment. However, recent discoveries of TDE
candidates by small scale infrared (IR) searches targeting luminous infrared galaxies (LIRGs), starbursting galaxies that are host to copious amounts of dust, suggest LIRGs may in fact have inflated rates of TDEs, hidden from view in the optical due to significant
dust extinction. In this talk I present a case study of the extremely IR-energetic nuclear transient AT 2017gbl, discovered as part of a targeted IR monitoring program of LIRGs. AT 2017gbl was barely detected in the optical, which prohibited traditional classification
through optical spectra. Instead, a large follow up effort ranging from the X-ray through adaptive-optics assisted IR photometry to very large baseline radio interferometry was conducted to determine the properties and nature of this transient. The analysis
of this extensive data set provided lots of puzzle pieces, and I will discuss whether they fit together to show a luminous supernova, a TDE, or perhaps increased accretion by an active galactic nucleus.</div>
