Despite this\, DCR can also be employed as a\ntool to ex tract additional color information from astrometry. M dwarf\nflares are pa rticularly well suited to this technique due to their\nubiquity across var ious regions of the sky\, and the dramatic contrast\nbetween the red photo sphere and blue flare emission. While flares are\nchallenging targets for sky surveys due to their short durations\, DCR\ncan be used to infer color temperatures across the unprecedentedly\nlarge sample of flares that will be detected in next-generation\nastronomical surveys\, such as the Legacy Survey of Space and Time\n(LSST) that will be carried out by the Vera C. Rubin Observatory\,\nstarting in 2025. By combining Rubin’s high image qua lity and\nastrometric precision with the truly massive amount of data it w ill\nproduce over 10 years\, DCR can be used to carry out a population-lev el\nstatistical analysis of stellar flare temperatures\, constraining\nmod els of energy release in stellar atmospheres and informing\nhabitability s urveys. We additionally validated this technique on\nflare data obtained f rom an LSST precursor\, the Deeper\, Wider\, Faster\nProgramme\, and showe d how certain choices made when modeling the\nspectral and geometric prope rties of the flare could lead to\noverestimating the true flare temperatur e.

In these settings\, atomic nuclei\nrapidly absorb neutrons before they c an decay\, building up very heavy\nelements in what scientists call the “r -process.” The first direct\nevidence for this process came in 2017\, when a glow known as a\nkilonova was observed following the gravitational wave event GW170817\,\nconfirming that merging neutron stars are an important source of heavy\nelements. However\, observations of old stars in our Gala xy suggest\nthat neutron star mergers alone may not explain all of the hea vy\nelements in the universe.\n\nHeavy elements form in mergers when neutr on-rich matter is ejected\ninto space\, typically from a dense disk of mat erial surrounding the\nnewly formed black hole. Similar disks can also ari se when massive\,\nrapidly rotating stars collapse—so-called “collapsars.” In\nespecially massive cases\, these disks may become unstable and fragme nt\ninto multiple low-mass neutron stars\, which could then merge with one \nanother inside the same environment. This process would generate\nrepeat ed gravitational wave and light signals—a kind of\n“multi-messenger sympho ny.” Recent reports of possible unusually\nlow-mass neutron star mergers a ssociated with supernovae may offer\nsupport for this idea.\n\nAnother pos sible source of heavy elements comes from giant eruptions\nof highly magne tized neutron stars\, known as magnetars. During these\nrare flares\, mate rial from the star’s crust can be blasted into\nspace.

In active galactic nuclei (AGN)\,\nradiation pressure on dust lau nches large-scale winds that couple\nenergy from the black hole to the sur rounding galaxy. In star-forming\nmolecular clouds\, dust mediates the eff ects of stellar radiation\,\nregulating star formation and disrupting clou ds on local scales.

In addition to providing\nthe commun ity with a spectral database applicable to a wide range of\ninvestigations \, it is optimized to address three core science goals:\nto survey the lar ge scale structure of the Universe for signatures of\nnon-Gaussianity duri ng inflation\; to conduct intensity mapping studies\nof the extragalactic background light for probing the history of\ngalaxy evolution\; and to sur vey the plane of the Milky Way for the\nprevalence and distribution of wat er and other biogenic ices. In this\nseminar\, I’ll provide an overview of the mission with a focus on the\ninstrument’s design and implementation\, including the laboratory\ntesting campaign and in-flight performance quan tification. We’ll\nalso look at the exciting early results emerging from t he first\ncomplete all-sky survey data.

Th ey've been observed to be well separated by their gamma-ray\nduration into 'short' and 'long' (and sometimes even 'ultralong')\,\nwith this binary c lassification being seemingly well described by\nbinary progenitor paths: long GRBs come from massive stellar deaths\,\nwhile short GRBs come from c ompact object mergers. Type Ia supernovae\n(SNe Ia) have similarly been lo ng-studied and are oft used as\nstandardizable candles for cosmology. Whil e the community agrees that\nmost SNe Ia are created from the explosion of a white dwarf star in a\nbinary\, research is still on-going on the ident ity of the binary\, the\nmass and composition of white dwarf\, and the exp losion mechanism\,\nspeed\, and location. In this talk\, I share with you some of my ongoing\nwork involving James Webb Space Telescope (JWST) obser vations of the\nlongest GRB ever\, GRB 250702B\, and the peculiar\, calciu m-rich SN\n2024kce.
