A multiwavelength view of the ISM in the merger remnant galaxy Fornax A

We present multi-wavelength imagery of the merger remnant galaxy NGC 1316 with an objective to study the dust content and its association with the other phases of the interstellar medium. Color-index maps as well as extinction maps derived for this galaxy reveal an intricate and complex dust morphology in NGC 1316, i.e. there is a prominent lane in the inner part, while at about 6-7 kpc it apparently takes the form of an arc-like pattern extending along the northeast direction. In addition to this, several other dust clumps and knots are also evident in this galaxy. The dust emission mapped using Spitzer data at 8 μm indicates even more complex morphological structures of the dust in NGC 1316. The extinction curve derived over the optical to near-IR bands closely follows the standard Galactic curve, suggesting similar properties of the dust grains. The dust content of NGC 1316, estimated from optical extinction, is ,- 2.13 × 10^5 M⊙. This is a lower limit compared to that estimated using the IRAS flux densities of ,-5.17× 10^6 M⊙ and the flux densities at 24, 70 and 160 p.m from MIPS ,-3.2× 10^7 M⊙. High resolution Chandra observations of this merger remnant system have provided an unprecedented view of the complex nature exhibited by the distribution of hot gas in NGC 1316, which closely matches the morphology of ionized gas and to some extent also the dust. X-ray color-color plots for the resolved sources within the optical D25 extent of NGC 1316 have enabled us to separate them into different classes.

Proteins and enzymes display excellent recognizing, binding and catalytic properties that can be exploited to produce functional nanomaterials for biosensing and biocatalytic applications. However, fragile nature of the biomolecules seriously hampers their application potential in biotechnology. As a result, various methods such as sol-gel chemistry, intercalation or molecular wrapping using organoclay oligomers or via microemulsion methods have been used to produce bioinorganic nanocomposites with functionally intact biomolecules. Herein, we show a simple method for the encapsulation of single heme protein using inorganic host matrix. In general, aqueous mixture of tri block-co-polymer such as PEO-PPO-PEO and myoglobin produced polymer-protein nanoconjugates where protein molecules were specifically associated with the hydrophilic-PEO functionality of the block-co-polymer. Subsequently, dispersion of lyophilized powders of protein-polymer composite in cyclohexane produced reverse-micelles contained intact protein molecules. Injection of stichiometric amounts of TMOS precursor to above solution produced discrete core-shell nanoparticles containing met-myoglobin. Various physico-chemical characterization techniques such as Transmission electron microscopy （TEM）, Energy disperse X-ray（EDX）, Fourier-transform infrared spectroscopy spectra （FTIR）, and UV-vis spectroscopy were used to characterize bio-inorganic nanoconjugates. TEM analysis of samples taken directly from the reverse-micelle solution showed the presence of discrete spheroidal electron-dense nanoparticles with mean diameter of 4.5 nm and was in good agreement with the molecular size of the native myoglobin （4.5 x 2.5 x 3.5 nm）, which suggested that individual protein molecule was wrapped with a ultrathin sheath of silica. EDX analysis of bio-inorganic nanoconjugates indicated the presence of elements Fe, S from myoglobin and Si from inorganic matrix. FTIR spectroscopy showed vibration modes at 460 cm-1 （Si-
