z~2 dual AGN host galaxies are disky: stellar kinematics in the ASTRID Simulation
Ekaterine Dadiani, Tiziana Di Matteo, Nianyi Chen +6
We study dual AGN host galaxy morphologies at using the ASTRID simulation, selecting black hole (BH) pairs with small separation (), high mass ($M_{\text{BH,12…
Partition function approach to non-Gaussian likelihoods: macrocanonical partitions and replicating Markov-chains
Maximilian Philipp Herzog, Heinrich von Campe, Rebecca Maria Kuntz +2
Monte-Carlo techniques are standard numerical tools for exploring non-Gaussian and multivariate likelihoods. Many variants of the original Metropolis-Hastings algorithm have been p…
Optimal Summary Statistics for X-ray Polarization
Jeremy Heyl, Denis González-Caniulef, Ilaria Caiazzo
We develop two new highly efficient estimators to measure the polarization (Stokes parameters) in experiments that constrain the position angle of individual photons such as scatte…
BridgeHand2Vec Bridge Hand Representation
Anna Sztyber-Betley, Filip Kołodziej, Jan Betley +1
Contract bridge is a game characterized by incomplete information, posing an exciting challenge for artificial intelligence methods. This paper proposes the BridgeHand2Vec approach…
Unique continuation on planar graphs
Ahmed Bou-Rabee, William Cooperman, Shirshendu Ganguly
We show that a discrete harmonic function which is bounded on a large portion of a periodic planar graph is constant. A key ingredient is a new unique continuation result for the w…
What are the parities of photon-ring images near a black hole?
Ashish Kumar Meena, Prasenjit Saha
Light that grazes a black-hole event horizon can loop around one or more times before escaping again, resulting for distance observers in an infinite sequence of ever fainter and m…
