The Role of Stellar Spin in Repeating Partial Tidal Disruption Events
Ananya Bandopadhyay, Benjamin Amend, Eric R. Coughlin +3
The repeated tidal stripping of a star by a supermassive black hole, known as a repeating partial tidal disruption event (rpTDE), can give rise to a transient that rebrightens mont…
Repeating Nuclear Transients from Repeating Partial Tidal Disruption Events
Ananya Bandopadhyay, Eric R. Coughlin, Julia Fancher +2
Extragalactic nuclear transients that exhibit repeating outbursts can be modeled as the repeated dynamical interaction between bound stars and supermassive black holes (SMBHs). A s…
The Maximum Gravity Model for partial Tidal Disruption Events: Mass Loss, Peak Fallback Rate and Dependence on Stellar Properties
Ananya Bandopadhyay, Eric R. Coughlin, C. J. Nixon
A star entering the tidal sphere of a supermassive black hole (SMBH) can be partially stripped of mass, resulting in a partial tidal disruption event (TDE). Here we develop an anal…
Comprehensive X-ray Observations of the Exceptional Ultra-long X-ray and Gamma-ray Transient GRB 250702B with Swift, NuSTAR, and Chandra: Insights from the X-ray Afterglow Properties
Brendan O'Connor, Ramandeep Gill, James DeLaunay +22
GRB 250702B is an exceptional transient that produced multiple episodes of luminous gamma-ray radiation lasting for ks, placing it among the class of ultra-long gamma-ray bur…
Predicting the Properties of the Fallback Rate from Tidal Disruption Events: Investigating the Maximum Gravity Model
Julia Fancher, Ananya Bandopadhyay, Eric R. Coughlin +1
A star destroyed by the tidal field of a supermassive black hole (SMBH) in a tidal disruption event (TDE) gives rise to a luminous flare. TDEs are being detected at an ever-increas…
The Double Tidal Disruption Event AT 2022dbl Implies That at Least Some "Standard" Optical TDEs are Partial Disruptions
Lydia Makrygianni, Iair Arcavi, Megan Newsome +37
Flares produced following the tidal disruption of stars by supermassive black holes can reveal the properties of the otherwise dormant majority of black holes and the physics of ac…
Repeated Tidal Interactions between Stars and Supermassive Black Holes: Mass Transfer, Stability, and Implications for Repeating Partial Tidal Disruption Events
Ananya Bandopadhyay, Eric R. Coughlin, C. J. Nixon
Stars orbiting supermassive black holes can generate recurring accretion flares in repeating partial tidal disruption events (TDEs). Here we develop an efficient formalism for anal…
A Potential Second Shutoff from AT2018fyk: An updated Orbital Ephemeris of the Surviving Star under the Repeating Partial Tidal Disruption Event Paradigm
Dheeraj Pasham, Eric Coughlin, Muryel Guolo +4
The tidal disruption event (TDE) AT2018dyk/ASASSN-18UL showed a rapid dimming event 500 days after discovery, followed by a re-brightening roughly 700 days later. It has been hypot…
Repeating nuclear transients from repeating partial tidal disruption events: reproducing ASASSN-14ko and AT2020vdq
Ananya Bandopadhyay, Eric R. Coughlin, C. J. Nixon +1
Some electromagnetic outbursts from the nuclei of distant galaxies have been found to repeat on months-to-years timescales, and each of these sources can putatively arise from the…
Measuring Neutron Star Radius with second and third generation Gravitational Wave Detector Networks
Ananya Bandopadhyay, Keisi Kacanja, Rahul Somasundaram +2
The next generation of ground-based interferometric gravitational wave detectors will observe mergers of black holes and neutron stars throughout cosmic time. A large number of the…
The Peak of the Fallback Rate from Tidal Disruption Events: Dependence on Stellar Type
Ananya Bandopadhyay, Julia Fancher, Aluel Athian +7
A star completely destroyed in a tidal disruption event (TDE) ignites a luminous flare that is powered by the fallback of tidally stripped debris to a supermassive black hole (SMBH…
Characterizing Gravitational Wave Detector Networks: From A to Cosmic Explorer
Ish Gupta, Chaitanya Afle, K. G. Arun +44
Gravitational-wave observations by the Laser Interferometer Gravitational-Wave Observatory (LIGO) and Virgo have provided us a new tool to explore the Universe on all scales from n…
Cosmic Explorer: A Submission to the NSF MPSAC ngGW Subcommittee
Matthew Evans, Alessandra Corsi, Chaitanya Afle +73
Gravitational-wave astronomy has revolutionized humanity's view of the universe, a revolution driven by observations that no other field can make. This white paper describes an obs…
Detectability of Sub-Solar Mass Neutron Stars Through a Template Bank Search
Ananya Bandopadhyay, Brendan Reed, Surendra Padamata +6
We study the detectability of gravitational-wave signals from sub-solar mass binary neutron star systems by the current generation of ground-based gravitational-wave detectors. We…
