Abstract We outline the “dark siren” galaxy catalog method for cosmological inference using gravitational wave (GW) standard sirens, clarifying some common misconceptions in implementation of this method. When a confident transient electromagnetic counterpart to GW event is unavailable, identification unique host general challenging. Instead, as originally proposed by Schutz, one can consult and implement dark siren statistical approach incorporating all potential galaxies within...
Abstract In the absence of numerous gravitational-wave detections with confirmed electromagnetic counterparts, “dark siren” method has emerged as a leading technique cosmology. The allows redshift information such events to be inferred statistically from catalogue potential host galaxies. Due selection effects, dark siren analyses necessarily depend on mass distribution compact objects and evolution their merger rate redshift. Informative priors these quantities will impact posterior...
Selenium pollution has been a topic of extensive research dating back further than the last decade and attracted significant attention from several environmental regulatory agencies in order to monitor control its discharge myriad industrial sources. The mining industry is prime contributor hazardous selenium release aquatic systems responsible for both acute chronic impacts on living organisms. Herein we provide an overview contamination issues, with specific focus industries, including...
We develop a method for implementing proposal on utilizing knowledge of neutron star (NS) equation state (EoS) inferring the Hubble constant from population binary (BNS) mergers. This is useful in exploiting BNSs as standard sirens when their redshifts are not available. Gravitational wave (GW) signals compact object binaries provide direct measurement luminosity distances, but redshifts. Unlike past, here we employ realistic EoS parametrization Bayesian framework to simultaneously measure...
Abstract Gravitational-wave (GW) observations from neutron stars (NSs) in a binary system provide an excellent scenario to constrain the nuclear parameters. The investigation of Pratten et al. has shown that ignorance f -mode dynamical tidal correction GW waveform model NS can lead substantial bias measurement properties and equations state. In this work, we investigate parameters resulting correction. addition, work demonstrates sensitivity estimated constraints on future observations. We...
Selenium (Se) contamination in natural waters impacted by anthropogenic activities is becoming a prevalent and widespread problem. Investigation of novel, low-cost, sustainable food-waste-sourced adsorbents for Se removal has largely been unexplored. Here, we report on the Se(IV) biosorption from liquid solution using three waste-derived/low-cost biosorbents, namely citrus peels (bare), Ca-alginate gel beads, Ca-alginate-citrus composite beads (Ca-alginate@citrus). The entrapment not only...
Abstract Low-rank coal such as the in Powder River Basin (PRB) is typically direct shipped without any need for upgrading. Due to lack of on-site processing capabilities, that mixed with out-of-seam dilution during mining process left mine pit. In some cases, loss could amount 5% total reserve. Research conducted on laboratory and pilot-scale pneumatic air table separators indicates sufficient upgrading can be achieved +1 mm fraction reject material meet typical end-user specifications....
In recent years, the demand for rare earth elements (REEs) has grown due to increasing and global supply shortage. The deficit of these critical encouraged search new sources, with coal byproducts as possibilities. Coals from certain parts world can be rich in REEs approach a total concentration 1,000 ppm. Two Alaskan samples, Healy Wishbone Hill, were investigated effects density particle size on REE concentrations three selected fractions, flotation tests conducted finer fractions....

Rare earth elements (REEs) have been identified as valuable and critical raw materials, vital for numerous technologies applications. With the increasing demand supply gap in REEs, many research studies focused on alternative sources of REEs.

Gravitational waves (GWs) from binary neutron stars (BNSs) are expected to be accompanied by electromagnetic (EM) emissions, which help identify the host galaxy. Since GW events directly measure their luminosity distances, joint GW-EM observations BNSs study cosmology, particularly Hubble constant, unaffected cosmic distance ladder systematics. However, detecting EM counterparts BNS mergers is not always possible. Additionally, tidal deformations of components offer insights into star (NS)...
