Rhodes Hall capture historic first girl’s basketball title

first_imgWESTERN BUREAU:Rodene Morris was on fire in Thursday’s final of the Western Basketball Association-ISSA Girls’ Open Championship top-scoring with 32 points to lead Rhodes Hall High to their first-ever title, a 50-37 victory over Spot Valley High at the Montego Bay Cricket Club.Holland High edged Mt. Alvernia High 28-27 in a tense third-place match that preceded the final.Morris’ all-round athletic ability was on full display as she not only scored at will, but also made herself useful as part of a strong Rhodes Hall second-half defensive effort, grabbing two rebounds to go with two blocked shots and three steals. Her teammate, Keron Brown, added 12 points and two steals in the historic win.The bulk of Spot Valley’s points came from Nassan-Gay Ricketts, who had 18 points, five rebounds, three steals and two assists, mostly in the first two quarters. But her endeavour was outdone by the talented Morris.easy lay-upHer easy lay-up, immediately after the tip-off, gave Rhodes Hall the first bucket of the afternoon and thereafter Morris needed little invitation to shoot as she took full advantage of some indecisive Spot Valley defending, especially in the last quarter.Notwithstanding, it was Spot Valley who held the lead at the end of the first quarter, with Ricketts doing the bulk of the work early on for a 12-9 margin.Ricketts and Brown combined well in the second quarter and it looked then that they were well on their way to the crown, outscoring Rhodes Hall 11-8 in the second stanza for a 23-17 lead at the half-time break.It was a completely different scenario in the third quarter, however, as Rhodes Hall, led by Morris, found their groove, making shots after shots to pull the game back after three keenly contested quarters at 29-28.Spot Valley never recovered and it gave Brown and Morris the fuel needed to win it for their school with a flurry of points in the paint, to waltz to a first-ever high school title, boy or girl, in the school’s history.Both schools will now turn their attention to the all-island play-offs set for GC Foster College.last_img read more

Astronomers uncover properties of a molecular outflow feature in a nearby starburst

Credit: Walter et al., 2017. © 2017 Phys.org More information: Dense Molecular Gas Tracers in the Outflow of the Starburst Galaxy NGC 253, arXiv:1701.05040 [astro-ph.GA] arxiv.org/abs/1701.05040AbstractWe present a detailed study of a molecular outflow feature in the nearby starburst galaxy NGC 253 using ALMA. We find that this feature is clearly associated with the edge of NGC 253’s prominent ionized outflow, has a projected length of ~300 pc, with a width of ~50 pc and a velocity dispersion of ~40 km s^-1, consistent with an ejection from the disk about 1 Myr ago. The kinematics of the molecular gas in this feature can be interpreted (albeit not uniquely) as accelerating at a rate of 1 km s^-1 pc^-1. In this scenario, the gas is approaching escape velocity at the last measured point. Strikingly, bright tracers of dense molecular gas (HCN, CN, HCO+, CS) are also detected in the molecular outflow: We measure an HCN(1-0)/CO(1-0) line ratio of ~1/10 in the outflow, similar to that in the central starburst region of NGC 253 and other starburst galaxies. By contrast, the HCN/CO line ratio in the NGC 253 disk is significantly lower (~1/30), similar to other nearby galaxy disks. This strongly suggests that the streamer gas originates from the starburst, and that its physical state does not change significantly over timescales of ~1 Myr during its entrainment in the outflow. Simple calculations indicate that radiation pressure is not the main mechanism for driving the outflow. The presence of such dense material in molecular outflows needs to be accounted for in simulations of galactic outflows. Explore further (Phys.org)—An international team of astronomers led by Fabian Walter of the Max Planck Institute for Astronomy in Germany has revealed essential properties of a molecular outflow feature in the nearby starburst galaxy designated NGC253. The findings were presented in a paper published Jan. 18 on the arXiv pre-print repository. NGC 253, also known as the Sculptor Galaxy, is an intermediate spiral starburst galaxy in the constellation Sculptor some 11 million light years away. The galaxy is one of the brightest spiral galaxies visible and also one of the dustiest. Due to its proximity and the fact that it is currently undergoing a period of intense star formation, it serves as one of the best laboratories to study starburst–driven galactic–scale winds in detail.NGC 253 is known for the galactic wind emerging from its central area, which carries significant amounts of molecular gas. In order to better characterize this emission, Walter and his team carried out a series of observations between November 2013 and August 2014 utilizing the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile. This observational campaign allowed the researchers to uncover crucial properties of the studied molecular outflow.”We present a detailed study of a molecular outflow feature in the nearby starburst galaxy NGC 253 using ALMA,” the paper reads.According to the study, NGC 253’s most prominent outflow feature towards the south has a projected length of about 978 light years, a width of approximately 163 light years, and a velocity dispersion of 40 km s−1. The scientists note that its extent and dispersion are consistent with an ejection from the galaxy’s disk starting about 1 million years ago.The kinematics of the molecular gas in this feature show that the material is approaching us and is also accelerating. However, the astronomers were unable to determine whether or not the molecular mass entrained in the outflow will escape the galaxy, or be recycled to fuel later episodes of star formation. More observations are required to draw final conclusions.”The kinematics of the molecular gas are consistent with accelerating with a velocity gradient of 1 km s−1 pc−1, and at its last measurable point it approaches the escape velocity. (…) More sensitive ALMA observations will trace the outflow even further out, and will shed light on whether or not part of the ejected molecular material will escape the galaxy,” the researchers wrote in the paper.The team also discovered bright tracers of dense molecular gas like HCN, CN, HCO+, CS in the molecular outflow. Moreover, they found that line ratios HCN/CO measured in the outflow are high and consistent with ratios observed in the central starburst region of NGC253 and in other starbursts, while the HCN/CO line ratio in the galaxy’s disk is significantly lower, which is typical for gas in the disks of nearby galaxies. The researchers concluded that this indicates that the dense molecular gas is retaining its properties in the process of its ejection from the central regions into the outflow.
