JWST and Keck Observations of the Off-Nuclear TDE AT 2024tvd: A Massive Nuclear Star Cluster and Minor-Merger Origin for its Black Hole
Kishore C. Patra, Ryan J. Foley, Nicholas Earl +10
We present JWST/NIRSpec and NIRCam observations of the first optically selected off-nuclear tidal disruption event (TDE), AT 2024tvd, along with Keck/KCWI integral field unit spect…
Constraining Collapsar r-Process Models through Stellar Abundances
Phillip Macias, Enrico Ramirez-Ruiz
We use observations of heavy elements in very metal-poor stars ([Fe/H] < -2.5) in order to place constraints on the viability of collapsar models as a significant source of the r-p…
Multi-Messenger Astronomy with Extremely Large Telescopes
Ryan Chornock, Philip S. Cowperthwaite, Raffaella Margutti +82
The field of time-domain astrophysics has entered the era of Multi-messenger Astronomy (MMA). One key science goal for the next decade (and beyond) will be to characterize gravitat…
r-process enrichment of ultra-faint dwarf galaxies by fast merging double neutron stars
Mohammadtaher Safarzadeh, Enrico Ramirez-Ruiz, Jeff. J. Andrews +3
The recent aLIGO/aVirgo discovery of gravitational waves from the neutron star merger (NSM) GW170817 and the follow up kilonova observations have shown that NSMs produce copious am…
Low-mass White Dwarfs with Hydrogen Envelopes as a Missing Link in the Tidal Disruption Menu
Jamie Law-Smith, Morgan MacLeod, James Guillochon +2
We construct a menu of objects that can give rise to bright flares when disrupted by massive black holes (BHs), ranging from planets to evolved stars. Through their tidal disruptio…
A Stringent Limit on the Mass Production Rate of -Process Elements in the Milky Way
Phillip Macias, Enrico Ramirez-Ruiz
We analyze data from several studies of metal-poor stars in the Milky Way, focusing on both strong (Eu) and weak (Sr) -process elements. Because these elements were injected in…
