The Astrophysical Journal, 2023 We present a novel fully Bayesian analysis to constrain short gamma-ray burst (sGRB) jet structures associated with cocoon, wide-angle, and simple top-hat jet models, as well as the binary neutron star (BNS) merger rate.

The Faint End of the Centaurus A Satellite Luminosity Function [PDF]
Astrophysical Journal, 2018 The Panoramic Imaging Survey of Centaurus and Sculptor (PISCeS) is constructing a wide-field map of the resolved stellar populations in the extended halos of these two nearby, prominent galaxies.

Evolution of Galaxy Luminosity Function and Luminosity Function by
Density Environment at 0.03
, 2006 Using galaxy sample observed by the BATC large-field multi-color sky survey and galaxy data of SDSS in the overlapped fields, we study the dependence of the restframe $r$-band galaxy luminosity function on redshift and on large-scale environment.

Axions and the luminosity function of white dwarfs: the thin and thick discs, and the halo [PDF]
, 2018 The evolution of white dwarfs is a simple gravothermal process of cooling. Since the shape of their luminosity function is sensitive to the characteristic cooling time, it is possible to use its slope to test the existence of additional sources or sinks ...

Luminosities of Carbon-rich Asymptotic Giant Branch stars in the Milky Way [PDF]
, 2013 Stars evolving along the Asymptotic Giant Branch can become Carbon-rich in the final part of their evolution. They replenish the inter-stellar medium with nuclear processed material via strong radiative stellar winds.

Padé Approximant and Minimax Rational Approximation in Standard Cosmology
Galaxies, 2016 The luminosity distance in the standard cosmology as given by ΛCDM and, consequently, the distance modulus for supernovae can be defined by the Padé approximant.

The Faint End of the z = 5 Quasar Luminosity Function from the CFHTLS [PDF]
, 2017 We present results from a spectroscopic survey of z ∼ 5 quasars in the CFHT Legacy Survey. Using both optical color selection and a likelihood method, we select 97 candidates over an area of 105 deg2 to a limit of iAB < 23.2, and 7 candidates in the ...

The Quasar Luminosity Function [PDF]
Symposium - International Astronomical Union, 1996 Recent results at high redshifts are briefly reviewed. An analysis of the evolution of the quasar luminosity function based on the recently published Hawkins & Véron (1995) variability-selected quasar sample is presented. The results support the conclusions of earlier work that suggested the simple two power law luminosity function, of invariant ...
