We present a scenario for the production of dynamically cold rings around the Milky Way via a high– eccentricity, flyby encounter. These initial conditions are more cosmologically motivated than those considered in previous works. We find that the encounters we examine generically produce a series of nearly dynamically cold ring–like features on low–eccentricity orbits that persist over timesca...

If cosmic rays with energies <100 TeV originate in the galaxy and are accelerated in shock waves in shell-type supernova remnants (SNRs), gamma-rays will be produced as the result of proton and electron interactions with the local interstellar medium, and by inverse Compton emission from electrons scattering soft photon fields. We report on observations of two supernova remnants with the Whippl...

We study the large-scale magnetic field structure and its interplay with gas dynamics in Monoceros OB1 East molecular cloud. combine observations of dust polarised emission from Planck telescope CO line Taeduk Radio Astronomy Observatory 14-metre telescope. calculate strength plane-of-the-sky using a modified Chandrasekhar-Fermi method estimate mass over flux ratios different regions use compar...

Visual and observer aerial surveys are important for monitoring wildlife populations but subject to visibility biases where animals may go undetected. The use of infrared technology in has the potential reduce biases, both when recording data retrospective processing footage, thus complements visible wavelength photography. We used video during marine mammal high-Arctic indirectly detected narw...

Pink shrimp (Metapenaeus affinis) or Jinga is one of the species caught in waters off Samboja Kuala. This catch a valuable commodity market. The possibility exploiting resources will be jeopardized an effort to conserve, utilize, and high intensity shrimp. study was conducted from September December 2022 with aim determining population dynamics parameters using frequency method carapace length ...

Penaeid prawns M. dobsoni of two different size ranges were ablated both unilaterally (UEA) and bilaterally (BEA) and subjected to individual study. The UEA prawns consumed almost the same amount of food as the control prawns in the size group, 35-40mm, but consumed about 57.8% more food than the control prawns in the larger size group, 48-53mm. Growth was estimated as length and weight changes...
