turnout, and the discussion was very successful, making for a great start to the series! </span></div>

Stellar Initial Mass Function'.</span></div>

<p style="line-height: normal; margin: 0px;"><span style="font-family: Aptos, Arial, Helvetica, sans-serif; font-size: 12pt; color: rgb(0, 0, 0);">Abstract: Over the decades active galactic nuclei (AGN) have moved from being esoteric objects to being a fundamental
part of galaxy evolution via feedback processes. There is now (almost) universal consensus that AGN are powered by accretion onto supermassive black holes. However, this was not the first explanation and even after it was first proposed in the mid-1960's,
the idea took decades to become firmly accepted. In this talk I will review some of the early ideas put forth to explain the origin of the power produced by quasi-stellar objects. These include exotic supernovae, stellar collisions, massive super-stars as
well as stranger ideas. I will then look to see if we can learn anything from these ideas. </span></p>

<p style="line-height: normal; margin: 0px;"><span style="font-family: Aptos, Arial, Helvetica, sans-serif; font-size: 12pt; color: rgb(0, 0, 0);">Abstract: Dust makes up only about one percent of the interstellar medium by mass, yet it has absorbed and re-radiated
roughly half of all the starlight ever emitted. It plays a central role in ISM physics: it catalyses the formation of molecular hydrogen, depletes metals from the gas phase, and regulates the heating and cooling of astrophysical gas. But for all its importance,
we remain in the dark about much of it, from where the earliest dust came from to what produces some of its strongest spectral fingerprints.</span></p>

infrared revolution of IRAS, Spitzer and JWST, this talk tours the Universe that dust both hides and reveals — from buried starbursts to complex carbon grains in the first billion years. Along the way we’ll take a few detours, including dust as an impostor
and as the subject of a rock star’s PhD. We’ll also meet the unsolved problems waiting for the next generation of astronomers. </span></p>
