Laguerre reconstruction of the BAO feature in halo-based mock galaxy catalogues
Farnik Nikakhtar, Ravi K. Sheth, Idit Zehavi
Fitting half-integer generalized Laguerre functions to the evolved, real-space dark matter and halo correlation functions provides a simple way to reconstruct their initial shapes.…
Laguerre reconstruction of the correlation function on Baryon Acoustic Oscillation scales
Farnik Nikakhtar, Ravi K. Sheth, Idit Zehavi
The baryon acoustic oscillation feature can be used as a standard cosmological ruler. In practice, for sub-percent level accuracy on the distance scale, it must be standardized. Th…
Galaxy properties as revealed by MaNGA. III. Kinematic profiles and stellar population gradients in S0s
H. Domínguez Sánchez, M. Bernardi, F. Nikakhtar +2
This is the third paper of a series where we study the stellar population gradients (SP; ages, metallicities, -element abundance ratios and stellar initial mass functions) of ea…
The Stellar Mass Fundamental Plane: The virial relation and a very thin plane for slow-rotators
M. Bernardi, H. Domínguez Sanchez, B. Margalef-Bentabol +2
Early-type galaxies -- slow and fast rotating ellipticals (E-SRs and E-FRs) and S0s/lenticulars -- define a Fundamental Plane (FP) in the space of half-light radius , enclosed…
Exact enumeration approach to first-passage time distribution of non-Markov random walks
Shant Baghram, Farnik Nikakhtar, M. Reza Rahimi Tabar +4
We propose an analytical approach to study non-Markov random walks by employing an exact enumeration method. Using the method, we derive an exact expansion for the first-passage ti…
The Excursion set approach: Stratonovich approximation and Cholesky decomposition
Farnik Nikakhtar, Mohammadreza Ayromlou, Shant Baghram +3
The excursion set approach is a framework for estimating how the number density of nonlinear structures in the cosmic web depends on the expansion history of the universe and the n…
