Internal Rotation in the Globular Cluster M53 [PDF]
Astrophysical Journal, 2017 Abstract We present an analysis of the internal bulk rotation in the metal-poor globular cluster (GC) NGC 5024 (M53) using radial velocities (RVs) of individual cluster members. We use RV measurements from a previous abundance study of M53 done using the Hydra multi-object spectrograph on the WIYN 3.5 m telescope.

Dominant negative mutants of the murine cytomegalovirus M53 gene block nuclear egress and inhibit capsid maturation. [PDF]
Journal of Virology, 2010 ABSTRACT The alphaherpesvirus proteins UL31 and UL34 and their homologues in other herpesvirus subfamilies cooperate at the nuclear membrane in the export of nascent herpesvirus capsids. We studied the respective betaherpesvirus proteins M53 and M50 in mouse cytomegalovirus (MCMV).

Unraveling the multifaceted resilience of arsenic resistant bacterium Deinococcus indicus [PDF]
Frontiers in Microbiology, 2023 Arsenic (As) is a toxic heavy metal widely found in the environment that severely undermines the integrity of water resources. Bioremediation of toxic compounds is an appellative sustainable technology with a balanced cost-effective setup.

Light Element Abundances and Multiple Populations in M53 [PDF]
Astronomical Journal, 2021 Abstract We present results from a study of 94 red giant stars in the globular cluster M53. We use low-resolution spectra to measure the strength of CN and CH features at ∼3800 and 4300 Å, respectively. The strengths of these features are used to classify stars into a CN-enhanced and CN-normal population and to measure C and N abundances

Study of globular cluster M53: new variables, distance, metallicity [PDF]
Astronomy and Astrophysics, 2009 We study the variable star content of the globular cluster M53 to compute the physical parameters of the constituting stars and the distance of the cluster. Covering two adjacent seasons in 2007 and 2008, new photometric data are gathered for 3048 objects in the field of M53.

RELATIVE AGE DIFFERENCE BETWEEN THE METAL-POOR GLOBULAR CLUSTERS M53 AND M92
Journal of the Korean Astronomical Society, 2016 CCD photometric observations of the globular cluster (GC), M53 (NGC 5024), are performed using the 1.8 m telescope at the Bohyunsan Optical Astronomy Observatory in Korea on the same nights (2002 April and 2003 May) as the observations of the GC M92 (NGC 6341) reported by Cho and Lee using the same instrumental setup.

CHEMICAL ABUNDANCES IN NGC 5024 (M53): A MOSTLY FIRST GENERATION GLOBULAR CLUSTER
Astrophysical Journal, 2016 ABSTRACT We present the Fe, Ca, Ti, Ni, Ba, Na, and O abundances for a sample of 53 red giant branch stars in the globular cluster (GC) NGC 5024 (M53). The abundances were measured from high signal-to-noise medium resolution spectra collected with the Hydra multi-object spectrograph on the Wisconsin–Indiana–Yale–NOAO 3.5 m telescope. M53

A multiband photometric study of RR Lyrae stars in M53 (NGC 5024)
New AstronomyWe present a multiband (UBVRI) time-series photometric study of RR Lyrae (RRL) stars in the globular cluster Messier 53 (NGC 5024) to refine their pulsation properties and determine a precise cluster distance. The archival photometric data includes images taken over 22 years and 3 months using different optical telescopes, providing an excellent time ...
